This bag filter (sometimes known as cassette filter) variant employs filter envelopes positioned horizontally in the housing. It also enjoys the advantage of a lower height.

Bag cleaning is achieved through a travelling carriage with a blast nozzle connected to a centrifugal blower. Travel of carriage is electronically controlled to sense row-by-row position stoppage & blasting in reverse direction.

Substantial saving is achieved in capital & running costs of REVERSE CLEANING air of a centrifugal blower, replacing Compressed air. These models are favourites in FOUNDRY applications.
