When dusty air enters the bin vent filter from a silo or surge bin, the air passes through a wall of filtration material, depositing any dust on the filter bag exterior. After passing through the bag, the clean, filtered air is exhausted to atmosphere. After time the deposited dust must be removed from the bag walls.

This is done through a quick pulse of compressed air traveling through a venturi to produce a shockwave which knocks the dust from the bag wall. Standard construction for a bin vent filter consists of a heavy-duty carbon steel welded body, interior safety grid, tool free 22” x 40” hinged maintenance door, exhaust vent, lifting lugs, and AEF white exterior. Bag cleaning is accomplished through an auto sequence reverse pulse timer housed in a NEMA-4 blow down enclosure. Bag condition can easily be monitored using the included differential pressure indicator.
