Application

Dust Collector Discharge

Discharges collected dust from under the filter bags against light negative pressure, at up to 120 °C.

Pain points

Dust ingress into the bearing
Fine dust migrates along the shaft and the bearing housing seizes within weeks. A double lip seal with a grease purge keeps the bearing cavity at positive pressure against the body.
Arching over the rotor
Collected dust is aerated and cohesive, so it arches above the inlet and then collapses in slugs. An inlet opening of 1.5 x pocket length on a full-pocket drop-through body moves it as a column.
Ignition risk in fine combustible dust
A dry-running rotor in fine dust is a spark path. Earthing studs on body and end cover plus a bronze-tipped rotor on request avoid metal-to-metal rubbing in the pocket.

Standard drop-through airlock for gravity discharge and vacuum feeding.

Ceramic liner or tungsten carbide coating for abrasive powders.
