Insertable Polygonal Dust Collectors for Negative Pressure Applications – WAMAIR Vacuum

A polygonally shaped Dust Collector for negative pressure pneumatic conveying applications.

WAM Insertable Polygonal Dust Collector

Filtering elements are inserted horizontally or vertically while a compressed air cleaning system is integrated in the access door. WAMAIR Vacuum is the ideal Dust Collector for negative pressure pneumatic conveying applications.

WAMAIR Vacuum is designed for use under up to -0.6 bar (-8.7 psi) of negative pressure. It is particularly suitable for de-dusting pneumatic conveying systems. Its technical features and its compressed air jet cleaning system enable continuous operation.

Its compact design makes this type of dust collector suitable for applications where limited space is an issue.
