AIR SHOWER (TOWER FLOW)

MODEL NO. - ACM-330TF

Our Material Handling Air Showers (tower flow) are

enclosed chambers ideally installed in front of a clean

room to prevent the entry of contaminating particles within

the working area. The Clean room air showers are

specifically designed for the elimination of surface

particles from the materials, clothes and skin surfaces of

the personnel, prior to entering a clean room or controlled

environment chamber. Our material handling air showers

find widespread use in semiconductor manufacturing

units, animal research facilities, pharmaceutical

production units, micro fabrication industry and in basic

and applied research laboratories.

open door push button is pressed. Once the user enters

the air shower cubicle, he/she can start the shower cycle

from the inside. The shower cycle is programmable and

can be set as per the requirements of the industry. Both

the doors of the unit remain locked till the shower cycle

continues, to prevent the entry of external contaminants

while the air shower is operational. Once the Tower flow air

shower cycle is completed, the personnel can exit through

the exit door. The one-way mode of operation allows the

user to enter the air shower cubicle, but he/she cannot exit

through the entrance door, therefore controlling the traffic

patterns into and out of the controlled environment

chamber. Moreover, the pre-purge function of our modular

air showers allows the unit to self-clean in a power-on

mode. The pre-purge time is also programmable and can

be set between 0-3 minutes. Air shower principle is based

on subjecting the personnel through adequate velocity of

clean air coming through a pre filter assembly.

Both the doors of our material handling Tower flow air

showers are interlocked and magnetically operated. They

are permanently energized and open instantly when the

WORKING PRINCIPLE

R


The air present in the air shower cubicle is continuously

circulated through the filter assembly, comprising of pre-

filters and HEPA filters. The filter assembly physically

entraps the contaminating particles and removes them

from the air circulation. The efficient fans and blowers blow

the filtered air into the air shower cubicle through

adjustable nozzles at appropriate face velocities. The

turbulent air streams produce enough shearing effect to

loosen the dust particles and other particulate matters

from the external surfaces, causing their wash down with

the air stream. The air shower cubicle is maintained at a

slightly higher pressure as compared to the outside to

prevent the contaminating particles from entering the

cubicle when the unit is at rest. Air Shower specifications

are in accordance with the US Federal Standards.

The unit is controlled through a programmable solid state

circuit control system, located at the junction box of the

unit. The junction box is a tamper proof enclosure that

houses emergency setting buttons for switching off of the

equipment in response to audio visual alarms. The control

unit houses the operation timer and nozzle adjustment

Our quality control air showers are equipped with top

mounted pre-filters and HEPA filters for the removal of

particulate matters as small as 0.3 microns in size with a

filtration efficiency of more than 99.97%. The pre-filters

can effectively remove around 85% of the particulate

matters, therefore reducing the contaminant load on the

HEPA filters and increasing their efficiency and life span.

The filtered air is released through adjustable nozzles,

arranged in a uniform pattern on the walls and ceilings.

The pre-filter unit is fully washable and is made up of non-

woven synthetic polyester, whereas the easy to clean

HEPA filters are made up of glass pleated non-woven

fabric filter.

buttons. Our air showers use microprocessor based

controllers for various set parameters and for the detection

of any errors or deviations from the set parameters.

Our air showers use top mounted fluorescent lights for

adequate illumination of the shower cubicle. The

fluorescent lights panel is concealed at the upper portion

of the unit and provides a minimum illumination of 800 lux.

The lighting arrangement conforms to the US Federal

standards.

Our air showers use heavy industrial grade mica clad

wooden boards and stainless steel (SS-304, SS-316) as

construction materials. The internal surfaces are

laminated and available in attractive finishes. The unit is

provided with interlocked and magnetically operated

doors on either side of the air shower cubicle. The doors

are made of aluminium panels and have clear view

glass/acrylic windows for increased visibility. The

compartment access panels are made of aluminium panel

and are hinged for ease of operation. Air shower room is a

closed cubicle with adjustable nozzles air showers

designed for clean room applications.
