WAMAIR® Dust Collectors consist of a polygonal shape 304 stainless steel casing, horizontally or vertically inserted filter elements, and a reverse air jet cleaning system integrated in the hinged access door. WAMAIR® Dust Collectors are either built in for venting applications or come as a stand-alone unit with dust collecting hopper. For suction, versions with an integrated fan are available.
WAMAIR® Dust Collectors separate dust from the air flow by means of pocket or special POLYPLEAT® filter elements. Dust drops down after an automatic reverse air jet cleaning device inside the front inspection door has removed it from the filter elements.
The dirty air flow may enter the filter casing from the top inlet flange where heavier particles are subsequently pre-separated while the flow is on the descent. Alternatively, dirty air may enter from the bottom flange which can be either connected to a WAM® PT-type hopper or to the device to be de-dusted (silo, belt conveyor, bucket elevator, chain conveyor etc.).
A special ATEX-version for zone 22 (category 3D equipment) is available.
