Problem:
Customer had several bins they fill with catalyst on a continual
basis. A small filter was required to vent the displaced gas. Space and
head room was at a premium and they did not want to modify the bins.
Solution:
A single pleated filter bin vent was designed to mount directly
on the customer’s bin ventilation flange. The filter housings are 304
stainless steel. A single solenoid valve/diaphragm valve is initiated by
a high pressure signal or timer. The use of a pleated filer gave the
same filter area as four felted bags, thus reducing the size of the unit
by 75%.
