Static/Dynamic Pass Box
It is used for transfer of material from one area
to another with isolation by means of Mechanical /
Electromagnetic door interlocking, which ensures opening
of only one door at a time. Thus avoiding cross contamination
between two area's.
The material to be transferred from one place to
another is placed within the hatch from one end and
the door is closed. And the material can be lifted
from the other end from the hatch. The interlocking
of the doors ensures only one door to be opened at
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 hatch 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
