Path of the LIFA Cleaning Concept

Consulting and guidance of customers

Inspection of need for cleaning

”Parallel” photos of Visual scale, robot aided video camera, comb and sampling method

Selection of cleaning devices:

Brushing and/ air-jetting machine, brushes+accessories, negative air

machine, disinfection devices etc

Verification of the cleanliness, photos of visual scale, camera, etc,

perhaps not the same as in the first phase

Brushes – 2 connection types

1) M12 screw connection (old type), for driller shafts, SC20

Soft – hard/stiff – combination=rect ducts – special vs.

2) Brush adapter connection for brushes with nylon center

Comparison of old vs. new type brushes inside duct

Disk in the center of the brush greatly enhances the speed of vacuum air flow

(manual) –

Cleaning agents, disinfectants, coatings

The ULV-technology = Ultra Low Volume is useful for quick disinfecting in the buildings and in ventilation systems.

There are two basic methods:

- Dry Fogging with by using Patriot PulsJet Fogger.

- Damp mist by using MacroMist aerosol aggregat.

These agents are peroxides.

For ductwork we are using the "wet aerosol method". The chemical used must be approved by local authorities for HVAC use (formaldehyde and chlorine based chemicals is an absolute no-no), also be aware that some chemicals corrode the duct or kill the the galvanasation.

GREASE CLEANING CONCEPT

Grease Cleaning Concept

• suitable for all types of grease, soft or hard-burned and both round and rectangular up to 1,2m in size

• unique capability of one machine capable of doing brushing, spraying chemicals and adsorbent granules all at the same time.

• Lifa machines are the only ones powerful and durable enough to be able to rotate a brush in a grease duct is also a decisive factor.

Grease Cleaning Concept

Different methods and techniques• Brushing (grease brush, cloth)

• Spreading of chemicals and brushing

• Spreading of oil adsorbent granules and brushing + air-jetting ALL AT THE SAME TIME

combined in one equipment package:• Effective for all types of grease

• In all sizes/shapes of ducts

• Machines can be used in other work also

Grease set equipment

SPREADING SIDE

Lifa brushing machine: unique

capability of brushing and air-

jetting/spraying liquids at the

same time

Lifa Granule Sprayer: can be

attached to CombiCleaner 40,

Special Cleaner 25 Multi (also

Hydmaster but then AirJet Combi

20 is needed too)

SUCTION SIDE

Lifa HepaClean machine: unique

filter options + combination

capability with superior vacuum

power

Lifa Preseparator Unit:

functionality and money

savings in less filter change

needs; attached to HC 2500,

HC 4000, AC 7000

Spreading side: Granule sprayer + Lifa brushing

machine

Special Cleaner 25 CombiCleaner 40 + 15 - pneumatic

Can be attached to

Hydmaster 40 also Granule Sprayer

Spreading side:

Granule + chemical spraying

• Hard grease that

doesn’t come off with

brushing need to be

softened with grease

detergent, foam best

• Liquidy grease is

adsorbed into oil

adsorbent granule,

then air-jetted and

brushed out into

preseparator

Nozzles for spraying chemicals and air-jetting

• BASIC SET (incl. In

machines): left ”liquid with

back pressure valve”; right is

”high volume air”

• ”foam nozzle”

• Y-nozzle small or big with

bending arms: for air-jetting in

rectangular ducts

Spreading side: brushes for grease cleaning

• Grease chopper 2 adjustable sizes: with Hydmaster and CC40/15 only, limited use

• Tynex brush: abrasive ”metal-sand-paper-like”; bristles bend = ”digs” into corners rectangular ducts

• Metal razor brush:100-400 mm Very sharp ends cuts both solid+sticky grease off. NEEDS TO BE EXACTLY OR SMALLER THAN DUCT !

• Grease brush with nylon center (hard duct brush): stiff 1,0 mm nylon bristles very hard, little bending = must be exactly or smaller than size of duct

• Grease brush M12: most ”aggressive” brush; 2,5 mm nylon bristles very stiff, no bending = must be exactly size of duc

Suction side: Preseparator (cyclone / gravitational

filter unit + Lifa negative air machine

Air flow is simply controlled

by damper: in minimum when

spreading granules, max when

brushing and/or air-jetting

Removes all heavy and greasy dirt

before normal filters into a waste bag

• easily removed and disposed

• savings in normal filters

Filter options

Prefilter box enables to use 2 different filters at the sametime, any combination: • EU4 (G4) bag filter or filter

mat• EU7 (F7) bag filter

• Lifa Fp7 particle and odourbag filter

• Hepa filter / gas filter
