These units are designed for applications where both
personnel and equipment are to be passed from one
area to another. During the process the personnel
or the equipment is subjected to high velocity of
sterile air for cleaning / removal of particles.
The fully gowned personnel enters from the inlet
door and waits within the unit for some time till
the exit door opens. During this period the timer
activates the blowers and the adjustable nozzles fitted
in the ceiling and walls of the unit deliver Class
100 filtered air jets at a velocity of Appx. 5000
FPM. Thus cleaning the fully gowned personnel or the
equipment to be transferred to the restricted area.
These units are factory assembled and are made up
of S. S. 304 grade Stainless Steel material. These
units have smooth welded corners.
A direct driven statically and dynamically balanced
blower assembly with a volume control damper is used
for air circulation within the cabinet. Easy access
is provided to the blower compartment.
DISCHARGE FILTERS :
Discharge filters are generally HEPA filters certified
to achieve an filtration efficiency of not less than
99.97% and filtration accuracy of 0.3 microns. Hence
the discharge air complies with Class 100 U.S. Fed.
Std. 209 - E.
Pre-filters made from the fibre glass media to achieve
high filtration efficiency and filtration accuracy
of upto 5.0 microns. These are used to block major
particles from the air within the unit being sucked
by the blowers and passing it through the discharge
filters. Thus enhancing the life of discharge filters.
Low voltage touch control panel in the front of the
cabinet is used for the unit operation. The unit comes
with the switchgear for safe & trouble free operation.
A MINIHELIC gauge is used for static pressure measurement
across the HEPA filters and also to monitor the blower
" Hour meter to record operation time.
" Static pressure transmitter. ( 4 - 20 mA )
" Variable blower speed control device.
" Germicidal U.V. light.
" Onsite validation.
