In the production process of electronic

components from condensers up to micro-

processors the purity of process liquids

is becoming more and more significant.

ultrafilter now offers innovative and

reliable products which comply with new

production standards while also guarantee

high production quality.

The special merits of the ultrafilter products are the following:

v economic processing

v short suspension/inaction and maintenance time

v minimum loss of raw materials

v maximum flow rates at low differential pressures

v low extractables

v minimum pre-rinse time

ultrafilter offers membranes with particle retention rates down to 0.04 µm depending

on the medium that you want to filter there is a wide range of elements and housings to

choose from.

The polypropylen-depthfilter which serve as a prefilter, have a high dirt hold capacity

and are the first link in the filtration chain. The last step is the membrane filtration with

retention rates of particles down to 0.04 micron.

ultrafilter in the electronic industry

7

Filtration of ultrapure water In the electronic industry the demand for de-ionised water of high purity is increasing.

In addition to the removal of particles there are more requirements that these filtration

systems must meet, e.g. short pre-rinse times after a filter change, a minimum migration

of extractables, as well a non disruption due to ion migration.

Furthermore, high flow rates and a low differential pressure are crucial parameters for a

cost effective filtration process.

The following picture shows the process in a RO-system schematically.

Prefilter In an RO-system the task of the prefilter

is to constantly supply the same water-

quality, independent from the changing

input parameters. This is particularly

important in order to protect the sensible

and expensive reverse osmosis mem-

branes.

Resin-catcher Frequently fine particles and dust are

washed out in the ion exchanger. This

leads to the blocking of the membrane

filters. That is why it makes sense and

is cost efficient to implement a depth

filter with an absolute retention rate and

a high dirt hold capacity behind the ion

exchanger.

Final filtrationDuring this final level before the point of

use a very fine filtration is necessary.

All particles and contamination up to a

size of 40 nanometers are held back by a

membrane filter, thereby guaranteeing

the best possible quality of the ultrapure

water and the manufactured products.

Circuit boardsThe present technique for producing circuit boards is the

so-called surface mount assembly. This technique requires

an extremely high purity and filtration quality of the process

liquids.

The following picture (pic. 2) shows a typical manufacturing

process. The de-ionised water and process liquids have

to be filtered while being cleaned. This must also be done in the course of

the different coating baths in order to ensure an optimal production process and to

minimize the amount of substandard products. Common contamination are metaloxides,

dust, undissolved salts and particles.

corresponding process parameters and

distinguish themselves by a high efficiency

and reliability.

Production of circuit boards


Compact disc, CD-ROM and DVDFor some years now Compact Discs have superseded and replaced records in the music

industry. In the computer industry the CD-ROM is the most widely used memory medium –

and its share in the market is still growing.

Filtration systems are also growing due to high quality requirements and standards

concerning storage density and capacity, the requirements for the materials used in the

production process.

A new generation of CD-ROMS with an even higher density the so called DVD-technique

(Digital Video Disc) continues this trend.

In order to avoid reading- and/or writing errors even the most insignificant contamination

and particles must be filtered out in all

process liquids and gases.

Picture 3 shows the manufacturing

process typical of a compact disc.

The following table lists those ultrafilter

products that are used in the

manufacturing of compact discs.

Every single product will be described in

detail in the following part of the catalog.

Hard disc drivesLike in the manufacturing of compact discs, increasing quality is also vital in

manufacturing of hard disc drives. The reasons for a consistantly better quality

of the input media are, as mentioned earlier, the result of a higher density of

memory as well as the development to reduce the indescribable gaps of the hard disc.

In the manufacturing process of hard discs great amounts of de-ionised water of highest

purity are needed. After the filtration the water must be free from interfering particles,

e.g. in form of silicates or smallest contmination of bacteriological size.

In the cleaning and preparation of the board for coating with nickel, the used process

liquids also have to be filtered in order to guarantee a consistantly high quality of

production and minimum product rejections.

Pic. 4: Hard disc production

ultrafilter offers a broad variety of filters

and housings for the production of hard

discs and the corresponding process

liquids (see pic. 4).

Independent from outer influences or

variations in the quality of the used liquids

a constant quality of the final product is

ensured.

ultrafilter in the beverage industry

Beside the optically clarification of the final product the food and beverage industry

emphasizes the removal of bacteria and micro-organisms.

Consumers do not want fibers, particles of undissolved ingredients in their drinks.

Substances that would alter the taste and influence the product’s characteristic features

are also undesireable. Bacteria and other micro-organisms reduce the shelf

life and may eventually also lead to a change in taste.

Apart from the filtration of liquids, large amounts of compressed air, carbon dioxide (CO2)

and nitrogen (N2) are also needed in the food and beverage industry.

Those have to be filtered too, in order to ensure a consistantly high quality within the

given products.

ultrafilter offers a broad variety of filters

for applications in the food and beverage

industry. Individually tailored for different

applications and requirements, it is

always economic efficiency in combination

with security and reliability that is most

important. Examples of typical ultrafilter

applications of elements in the food and

beverage industry will become evident on

the following pages.

Steam

A good steam quality is necessary for the sterilization of the filters and the tanks,

because it enhances the service life of the filters and more importantly it guarantees a

constant product quality.

Application Process medium Recommended ultrafilter filter Pore size Page

Sterilization Saturated steam ultrex P-GS 1–25 µm 48

WaterWater is used for rinsing and cleaning of filling jets, bottles, kegs or other containers.

This water should be sterile, so that the rinsing does not result in contamination.

Water is also very often part of the final

process or even the final product itself.

Therefore one must recognize the im-

portance of the fine filtration of table-

or mineral waters, the sterile filtration

or bacteria reduction of water intended

for the addition to non-alcoholic drinks,

juices, beer or syrup.

Air- and gas filtrationOther gases than compressed air are commonly used such as carbon dioxide and nitrogen in the food and beverage industry.

These gases must be clean and free of particles and bacteria by hydrophobic membrane filters or by the patented ultrafilter sterile filter

ultradepth® P-SRF in order to guarantee the best possible quality of the product.

Aeration and de-aeration To avoid the contamination of storage tanks or transportation containers for water, wine, juices, liquid sugar or other liquids by

bacteria, the use of sterile vent filters is necessary. ultrafilter offers a wide choice of filters for every size and type of tank as well as for

various filling and emptying rates.

Aeration and de-aeration filters are designed to work under atmosphaeric conditions. For this reason a low differential pressure and a

reverse flow direction are the most important parameters, apart from a long service life and a high dirt hold capacity.

The housing should offer an optimized flow rate and a splash protection to protect the filter medium from the liquid inside the tank.

All these characteristics are combined in the ultrafilter aeration and de-aeration filter ultradepth® P-BE.

Various types of elements offer an efficient protection of the stored products.


Aeration and de-aeration Air ultradepth II P-BE 0.01 µm 46of storage tanks up to 99.999%


The filtration of wine should neither affect the taste nor the color of the wine.

ultrafilter offers depth and membrane filters for the filtration before filling and

cold stabilization after the D.E. filter.

This removes micro-organisms, bacteria and particles effectively without influencing the

“spirit of the wine”. A typical application in the filtration of wine is shown in picture 6.

BeerIn the production process of beer ultrafilter offers depth-

and membrane filters for the removal of particles, bacteria

and yeast. This process follows the Diatomaceous Earth

filtration (D.E. filter) before filling.

Not all breweries have sediment free water sources,

it is recommended, for these applications, to filter the

water in order to ensure a consistant input quality of the beer.

Picture 7 shows a typical process of beer production.

DairiesThe processing of milk in dairies can be described as follows:

In a first stage the milk is separated into creme and milk with a reduced fat content.

After this separation a thermal the milk is usually thermally treated (heated or chilled)

to reduce the amount of bacteria or prevent them from growing.

After this second stage the following process should take place under sterile conditions.

ultrafilter in thefood industry

Beside these products there are other so called sour milk products such as:

16

v Sterile storage of milk, milk product and additives

(e.g. fruit, water or flavors) only in sterile vented and bacteriophage

free tanks.

v Transportation of powder products only with sterile compressed air or

other sterile filtered gases.

v Purging of storage or holding tanks with a laminar flow of sterile air.

v Regular cleaning and sterilization with steam, sterile water

or chemicals.

v Aseptic filling and packaging of the final product under

a sterile atmosphere to prevent bacteria penetration.

Sterile means that equipment such as, storage or holding tanks, mixer, etc.

which comes into direct contact with the actual product do not cause any

bacteriological contamination.

The advantages of these sterile conditions are mainly:

v Best possible and consistent quality

v Extended shelf life of the product

v Reduction or exclusion of preservatives

v Protection from fermentation bacteria’s and no foreign growth

Sterile conditions improve the market potential of dairies because

a longer shelf life could allow them to develop new markets, reduce the

loss of products due to foreign growth in the fermentation process,

and improve of the manufacturing process ensuring consistent quality of

the product.

To achieve the required sterile conditions, ultrafilter offers a complete

range of products which meet the high demands of the dairy industry

and fulfil the requirement for contact with food according to FDA

regulations.

Sterile conditions can be achieved by

the following actions:

Packaging machinesThe food industry is heading more and more in the direction

of aseptic packaging or filling and away from thermal treat-

ment or preservatives to extend the shelf life.

This relatively new method has the advantage of an absolute

continuous process and a reduction in energy consumption,

a better flexibility to store the products and it also avoids the

necessity for the cooling of the product since the filling takes place under cold conditions.

ultrafilter offers specifically for these applications a large variety of solutions to improve the shelf life of the products without using

additional additives or preservatives.

One solution for this problem is the sterile air box P-SLF. The function of this system is sometimes integrated into the filling machine

by using pre- and sterile filters or the system is used as an external unit.

Infusion solvents, serums, vaccines, plasma. These are only some of the products of the

pharmaceutical industry that are produced to meet the highest standards concerning

quality and purity. ultrafilter offers filter systems which have been developed to match the

requirements of the pharmaceutical industry and biotechnology for numerous applications.

In order to ensure consistent quality of the final products the entire manufacturing

process must be free from any contamination. This aim is reached in a reliable, safe and

cost efficient way by ultrafilter membrane filters.

ultrafilter in thepharmaceutical industry and the biotechnology

Air and gas filtrationThe compressed air in fermentation processes is filtered before it is added to the

fermenter through the vent pipe. Nitrogen which is used for pressurizing tanks should

also be free from bacteria, pyrogenes and any other particles before it comes

in contact with the final product. ultrafilter sterile air filters distinguish themselves

by their inherent hydrophobia, a high dirt hold capacity and a low differential pressure.

The validated sterile depthfilter P-SRF as well as the membrane filters ultrapolymem®

and ultrateflomem® meet the highest quality requirements and have been proven their

performance in thousands of applications.

The fermentation process shown in picture 10 shows how ultrafilter filters are used in

this application.

Water filtrationThere are two relevant standards concerning the water quality for the pharmaceutical and

biotechnology industry:

v WFI, water for injection: This water meets the highest level of requirements. It is

used for the adjustment of product concentration, for the production of WFI steam,

and for the cleaning of ampoules or vials.

v PW, purified water or deionizied water (DI-water) is mainly used for cleaning of

bottles and ampoules or as a supply for fermenters. It is also an addition to lotions,

creams and used in the production of purest steam for sterilization.

For the production of these water

qualities ultrafilter offers the asymetrical

polyethersulfone membrane with retention

rates down to 40 Nanometers (= 0.04 µm).

This filter medium is characterized by

substantially high flow rates and a low

differential pressure.

Compared to traditional filter media

the differential pressure is 4 to 8 times

lower! For the end-user this means the

highest safety at low filtration costs.

Picture 11 shows a typical process of

sterile water treatment.

Water purification


22

Chemicals and solventsApart from water, chemicals and solvents are important complementary materials in

the production of pharmaceutical and biotechnical products. Alcohols, actetones and

methylene chlorid are the most frequently used products. All these chemicals are

aggressive and therefore the filtration systems have to be adjusted to meet these

requirements as well as the usual filtration quality.

Picture 12 shows the filtration of chemicals from raw materials to the final product which

the consumer will receive. The following tabulation lists those ultrafilter products which

are recommended for filtration to ensure a highly efficient and consistant quality, even

in the event that the quality of the raw materials should fluctuate.

Sterile filling of pharmaceutical andbiological productsFiltration by membrane guarantees sterility in filling pharmaceutical products. This

ensures an efficient retention of pyrogenes, living microorganisms and particles at a

maximum flow rate. As a prefilter for protecting the membranes ultrapolyplea® depth

filters are used. These filter elements have a high dirt hold capacity and low extractables.

In storage and holding tanks hydrophobic ultrafilter aeration and de-aeration filters

guarantee sterile conditions for storing the sensitive products and exclude a contami-

nation by the ambient air.

The following picture (picture 13) shows the process of sterile filling and the ultrafilter products designed for it.

The filtration of paint and ink is a particle filtration aiming at a consistently high quality of

the paint. In the automotive industry or in the printing industry impurities mean costly

rework or rejections.

In the electronic industry particles can cause read-/write errors at CD-ROMs.

Purity requirements are also growing concerning inks. In order to obtain a higher resolu-

tion of the prints, the nozzles that apply the ink are getting smaller. ultrafiter filter reduce

the costs for rework and maintenance on paint spraying tools effectively because all

foreign particles are removed.

This ensures a high quality of the final product.

ultrafilter –filtration of paint and ink

High Quality Paint FiltrationNew technologies of paint applications and new paint qualities allow the

end-user to reduce the thickness of the paint layer down to 500–700 µm.

For this reason the quality demand on the paint manufacturer increases.

Gels, foreign particles, fibres or filings have to be removed by a reliable

and save filtration process. This leads to a consistent quality of the paint

and prevents a blocking of the nozzles.

The different types of filters as well as a typical process is shown in

the following diagram.

Filtration of inkIn the filtration process of ink usually a continuous circulation is used. A filter

system has to ensure that the colour of the ink does not change and that

the color pigments are not removed, but disturbing particles only.

ultrafilter depth filters and their numerous different pore diameters always offer

the right solution for your application.

Maximum dirt hold capacities at low differential pressures reduce the costs of

filtration considerably and guarantee an optimum quality and long service life.

ultrapolymem® P-PF-PP

The ultrapolymem® P-PF-PP,

the membrane filter 100% from

polypropylene, the cost effective

alternative to PTFE

The membrane for the filtration of solvents, alcohols, chemicals

and gases.

SEM of the

ultrapolymem® membrane


The ultrapolymem® filter is a pleated poly-

propylene membrane filter, constructed of

100% pure polypropylene. It provides

maximum durability against chemicals in

critical processes. The filter media, poly-

propylene, is inherently hydrophobic, with

a highly porous membrane structure.

Therefore, a consistantly high porosity and

particle removal is guaranteed throughout

its entire service life.

For this reason the filter is especially suit-

able for the filtration of compressed gases,

fermentation of gases, technical gases,

tank ventilation and for solvents. ultrapoly-

mem® offers a cost effective alternative to

a PTFE membrane with similiar performance

and durability range against chemicals.

Features:

All components fulfill the FDA requirements

for the contact with food in accordance with

CFR (Code of Federal Regulations) Title 21.

ultrapolymem® filter elements have passed

the toxicological tests according to USP XX

Class VI for plastics. In particular, the

requirements of the chemical, biological,

cosmetic, electronic and the pharma-

ceutical industries are fulfilled.

The membrane is manufactured in accord-

ance with the cGMP requirements (current

Good Manufactuerer Practice), is non-fiber

releasing and is thermally welded without

the use of binders or other chemical

additives.

Applications:

The ultrapolymem® membrane is designed and developed for the following

applications:

For the filtration of aqueous solutions, the ultrapolymem® membrane must be mixed

with a liquid of lower surface tension e.g. IPA. Due to the inherently hydropholic filter

media, the ultrapolymem® membrane is also suitable for the filtration of gases in such

as:

v Acids

v Bases

v Alcohols

v Solvents

v Etchants

v Photoresists

v Photolithographical solutions

The ultrateflomem® P-PF-PT –

Teflon* membrane filter for

the filtration of aggressive solvents,

chemicals and gases

The membrane for the filtration of aggressive solvents, chemicals

and gases.

SEM of the

ultrateflomem® membrane


The ultrateflomem® filter is a pleated PTFE

membrane filter, which offers maximum

assurance of filtration performance and

durability range against chemicals in severe

process conditions. The filter element is

manufactured exclusively by the use of

Teflon* and polypropylene. The retention

rate extends from 0.1 µm to 1 µm (for

gases down to 0.01 µm).

The Teflon* filter media is inherently hydro-

phobic with a highly porous membrane

structure. This ensures high flow rates and

a high absorption of particles during the

entire service life. The endcaps and the

Teflon* membrane are thermally welded

without the use of binders. This results in

an integral filter cartridge which provides

maximum durability range against chemi-

cals with minimal extractables.

ultrex® P-GS

The ultrex® P-GS –

sintered stainless steel

steam filter

Applications:

The ultrex® filter is, among others, designed and developed for the following applications:

v Breweries

v Chemical industry

v Pharamaceutical industry

v Food and beverage

v Aseptic packaging

v Electronic industry

v Dairy industry

v Plastic industry


The ultrex® filter consists of a regenerable

weldless filter pipe made from sintered

stainless steel. The retention rate extends

from 1 µm to 25 µm.

Features:

The ultrex® filter retains contaminants,

such as particles, abrasion of valves and

sealings as well as rust. An improved

steam quality ensures longer service life

of the filters to be sterilized and increases

the efficiency of the entire process.

The ultrex® filter element offers the possi-

bility of a particularly economic filtration,

since the filter medium can be regenerated

by ultrasonic bath. This is especially es-

sential at high particle loads. The porosity

level is more than 50% which ensures high

particle and dirt holding as well as a good

flow rate at a low differential pressure.

The heavy-duty construction of the ultrex®

filter is designed to withstand a

maximum differential pressure up to 5 bar

(75 psid). The filter may also be used in a

temperature range of –20°C (–4°F) up to

210°C (410°F).

In order to meet these high requirements,

gases like oxygen, argon, helium or

nitrogen are filtered by the ultrafilter

ultrapure® – the pure gas filter R-EG and

its multilayered depthfilter medium R-TF.

Absolute retention rates of particles with

a size of only 0.01 µm guarantee a trouble-

free and a quantitatively consistent quality

of production.


The ultrafilter ultrapure® pure gas filter

consists of a 1.4404 (316L) stainless

steel housing. The housing is electro-

polished from the inside and has a surface

finish of Ra = 0.8. Inside the housing

features a multilayer depthfilter, a medium

that provides an absolute retention of

particles up to 0.01 µm. The ultrapure®

filter is prefered in the electronic industry

as a point of use filter for gases like

oxygen, argon, helium or nitrogen.

The electronic industry’s requirements concerning the

purity of auxiliary materials are rising together with the

growing memory density and efficiency of the electronic

elements.

ultrapure® R-EG

Applications:

The ultrapure® point of use filter is designed and developed for the following

applications:

v photo paint

v ion donation

v oxidation/diffusion ovens

v wafer drying

v aerospace technology

v filtration of solvents

v gas supply and automatic control systems

Benefits:

The ultrafilter ultrapure® gasfilter has been developed especially for the semiconductor industry, they retain particles up to a size of0.01 µm, in accordance with the correspondingstandards.

The high capacity to hold dirt and the high volume of the depthfilter medium R-TF result in long service life at low differential pressurewhich leads to low operating costs.

Special Viton o-rings and a clamp connection between the two parts of the housing form an efficient and safe protection against the escapeof gases.

No fibers or other particles migrate from the patented ultrafilter depthfilter medium R-TF. This guarantees the highest purety of the filtrateand a high quality of the production.

The particle retention up to 0.01 µm leads to the best possible efficiency of the filter and thedepthfilter medium R-TF ultradepth® leads to a long service life at a low differential pressure. This means that the use of ultrapure® gas filtersamortizies after a short while.

P-EG filter housings have been developed

for the purification of compressed air and

other technical gases in industrial ranges

of application. Due to the optimized

construction they offer low differential

pressure at high flow rates.

Numerous different sizes of housings with

various connections make it possible to

adopt the filter system to exactly the

needed requirements. In this product

series there are 18 different sizes of

housings for operating volume flows of

60 to 23.040 Nm3/h related to 7 bar(g)

(35 to 15.360 scfm related to 102 psig)

In the processing of perishable or sensitive products the demands

for hygiene are usually very high. The ambient air is polluted and

can ruin even the cleanest production process if it comes in contact

with the end product without being purified.

Bacteria, viruses, phages, oil mist, water and dust in the ambient

air are the main reasons for the microbiological spoilage of the

products.

Sterile air creates aseptic conditions in pressurized and in open

storage or mixing tanks and in filling machines.

A continuous exchange of the air cushion and a slight overpressure

in this critical area reduces the risk of a secondary contamination

with ambient air.

ultrafilter developed specially for these production processes where

bacteria and phage free air is required the autarkic sterile air box

P-SLF. With eight different sizes from 30 m3/h (18 cfm) to

960 m3/h (566 cfm) it is possible to produce sterile air in the most

cost efficient way. The P-SLF box is available in a mobile and a

stationary version and can be sanitized with saturated steam.

The P-SLF box is used in applications within the food and beverage,

the chemical, the pharmaceutical and the cosmetic industry.


The filtration system is a compact unit consisting of a pre- and

sterile filter with a low pressure blower.

The sterile air is transported with a very low overpressure into the

storage tank. This constant air exchange prevents the growth of

bacteria, viruses and phages which the ambient air contains.

Function:

The blower sucks the dry but polluted ambient air (r.H. < 95%) via the air intake (1) into

the chamber (2). The air is cleaned with the prefilter at the upstream side of the blower.

The retained particles cause an increase in the differential pressure. To maintain the

function of the system and to protect the blower (4) a vacuum relieve valve (3) is in-

stalled.

The blower (4) “compresses” the air at about 0.1 bar (1.5 psi). The compressed air is

fed into the sterile chamber (5). The sterile filter retains microorganisms and all kind of

bacteria and/or other contaminants.

To protect the blower there is also a pressure relief valve which opens if the sterile filter

is blocked. At the outlet (11) the sterile air is fed to the tank or an other point of use.

During sterilization of the sterile chamber and the sterile filter elements, the disc

valve (7) needs to be closed to prevent steam entering the blower. To maintain a good

steam quality the steam filter (8) is standard on the P-SLF box. After sterilization the

condensate can be drained out the discharge valve (9 + 10).

* Standard:

220 V/380 V , 50 Hz (P-SLF 0288-0 to 1152-0)

380 V/660 V , 50 Hz (P-SLF 1536-0 to 3072-0)

Also other voltage or frequencies availableon request.

Note:All P-SLF boxes are also available in PN 4version. This means it can be sterilizedwith saturated steam up to 4 bar (58 psi)or a steam temperature of 140°C (284°F).The name of such a box would e.g. be P-SLF 0576-4.

1. The Bubble Point Test

At the beginning of the bubble point test the membrane

has to be rinsed with an adequate wetting agent.

For hydrophilic membranes this is usually water, for

hydrophobic media isopropyle alcohol (IPA) or

an IPA-water mixture depending on the manufacturers

specifications.

After the element has been wetted sufficiently, the

remaining water is drained by the drain valve (V4).

The drain valve (V4), the aeration valve (V3) and the

valves at the upstream (V1) and downstream side (V2) are

closed. The valves V2 and V5 are opened. After that an air

pressure of around 70% of the expected bubble point

value is introduced through valve V2. For each membrane the

bubble point depends on the pore size.

The pressure is being risen by 0.1 bar steps until an even flow of air bubbles rises from

the free end of the tube that ends in a water filled container. Then the bubble point is

reached. The pressure has to be higher than the value given by the manufacturer in order

to prove that the filter element still has integrity.

The bubble point determines the “biggest” pore in the medium.

Test procedures to determinethe integrity of

sterile filter elements.In all critical applications and also all in all validated processes regular testing of the

integrity of the sterile filter elements is necessary. According to cGMP (current Good

Manufacturer Practice) tests have to be run before and after every sterilisation.

These integrity tests are related to destructive tests, e.g. the bacteria challege test.

The results are transfered to non-destructive tests. There are three different test

methods for membrane filters and one for sterile depth filters which are commonly used.

The following tests provide revealing, reproducible and reliable data on the qualities

and the condition of a filter element:

v bubble point test

v diffusion test

v pressure hold test

v DOP-test (dioctyle phthalate) for sterile depthfilters only!

Each of these tests has its very specific

field of relevance, which means that it

is only by the combination of at least two

different test methods, e.g. bubble point

and diffusion test, that a clear statement

concerning the integrity of a filter element

can be made.

The bubble point depends on various

factors:

1. temperature

2. filter medium

3. wetting agent

4. pore size

In order to get reproducible results the

parameters have to be the ones given

by the manufacturers.

Bubble Point Test

66

2. Diffusion test

The diffusion test measures the quantity of air diffusion

through the filter medium. Like in the bubble point test, the

element has to be rinsed with a wetting agent.

After this valves V1, V3, V4, and V6 are closed, V2 and V5

are opened. A pressure of approximately 70–80% of the

bubble point value is entered through valve V2 till it

stabilizes.

The diffusing air volume is measured by an inversed water

filled burette that is in a container with water. If the filter

element works correctly, only a certain air volume per minute

and filter is supposed to diffuse through the filter media.

This value depends on the type of filter, its medium and the

pore size, and will be indicated by the manufacturer.

The diffusion test states the membranes’ “average” pore size.

Diffusion values that are too high or too low may be due to a damaged filter or leakage in the filtration system.

3. The pressure hold test

The principle of the pressure hold test is the same as that

of the diffusion test. Apart from leakages in the membrane

filter even the smallest leakage of the filtration system

can be detected.

A distinction whether there is a leak or whether the mem-

brane lost integrity is not possible.

After a water- or IPA rinsing of the filter element the moisting

liquid is drained through valve V4, then valves V1 and V3 are

closed.

A pressure of approximately 70–80% of the expected bubble

point value is entered through valve V2 and after a short

period of stabilization of about 3 minutes readjusted again.

Valve V6 is kept open during that whole process.

After a certain time the pressure is supposed to drop only by a certain value in order to prove that the integrity of the filter element is

still assured.

The pressure drop does not usually leave the millibar range and therefore it is necessary to have very exact pressure gauges.

The pressure drop depends on pore size, filter medium and wetting agent. Furthermore the temperature has to be kept constant

during the measurement in order to get relevant results.

These three methods can be conducted manually but they require a lot of time and well qualified staff in order to avoid incorrect

measurements.

This is the reason why ultrafilter offers an automatic and sensitive integrity test system, the ultracheck vario®.

4. Dioctyle Phthalate Test (DOP)

The DOP test is only used to test the integrity of sterile depth filters and shows the retention rate of the filter elements.

The testing procedure is described by EN 1822 and by ASTM (American Society for Testing and Materials) D 2986-91.

An aerosol generator is used to produce a paraffin oil smoke with a particle spectrum of 0.1 to 0.5 µm. The test smoke is used to

moist the filter element. A laser particle counter counts the number of particles that pass the filter element. A “sterile” element has to

have a LOG reduction value (LRV) of more than 7 per cm2 filtration area. That means that out of 107 particles only 100 (= 1) particle

is allowed to pass per cm2 of the filtration area. Than the LRV is higher than 7 and the element is considered as “sterile”.

The Filter Test Center (FTC) is used to test the integrity of sterile depth filters.

For this purpose, the device carries out a DOP test (Dioctyle Phthalate test) according

to EN 1822 and ASTM D 2986-91 (see above). The efficiency of the filter element is

displayed.

Ease of operation and a menu driven user interface are the features of the FTC.

All operating sequences are shown in a LCD dispay. This means, the user is always

informed on what is currently going on and which steps have to be taken next.

The device automatically calibrates either after a set period of time or after a restart.

This ensures reliable and reproducible results at any time.

These results are evaluated (good/bad) and logged by a printer or they can be directly

requested via a serial interface to a PC.

The ultracheck vario® is used to check the integrity of membrane filters.

The electric-pneumatic instrument performs a pressure hold test and a bubble

point test. The results are compared to the critical data and a report about

the measurement is printed.

Exchangeable units help to adopt the ultracheck vario® to all types of filters

and pore sizes.

Because of its ease of operation and exact results the ultracheck vario® is

a safe and flexible instrument for the documentation of filter performance and

the intergrity of membrane filter elements.

77

Your compressed-air supply will become transparent due to the service of the ultrafilter

measurement techniques. We record the pressure, temperature and volume flow of the com-

pressed air on the site and determine the energy consumption of the compressor station.

These data are needed to determine exactly the quality of the compressed air in accordance

with the relevant standards. In case of the residual oil content measurement e.g., ultrafilter

records all liquid and gaseous contaminations in the user’s compressed-air network – down

to the verification limits.

These are services which pay for themselves quickly. The exact analysis of the actual conditi-

on is the optimum basis e.g. for the planning of adsorption dryers or for an enlargement of

existing compressed-air networks and preparation plants.

And – last not least – it provides safety: it ensures you that the compressed air in the

network corresponds to the individual quality requirements.

Saving by planning: The ultraplanning system guarantees replacement parts, such as

filter elements, at a fixed price for three years.

Your maintenance costs can be easily calculated. A further advantage:

ultrafilter is also responsible for the delivery of the filter elements in time.
