Our MFD range of reverse jet filters operates by compressed air cleaning and is able to accommodate a filtration area of up to 2,000 m² in one filter housing. Custom-build to specification, this dust extraction system offers lower capital investment cost to a similar reverse air cleaning filter, at least if smaller sizes are concerned. Large front doors enable a quick and easy access for maintenance operations.

Functional description

The surface filter MFD operates fully automatically with a compressed air cleaning system. This custom-made filter allows economic operation with a constantly low filter differential pressure. Compared to the reverse air filter the capital expenditure is considerably lower. The control of the cleaning impulses is carried out electro-pneumatically. Impulse and interval times can be regulated.


The filter housing is constructed of reinforced welded steel sheet. Airtight doors allow access to the clean gas chamber. The filter element consists of individual filter bags and inserts with spanners. The filter elements, stretched via locking fastener, are easy to maintain and can be removed from the front.

In particular the cleaning device consists of:

  • Easy to dismantle nozzle pipes
  • Membrane valve
  • Valve control units
  • Compressed air manifold.
