Dust filters

DCP’s compressed air cleaned envelope filters can be broadly divided into three main groups:

  • Cased filters
  • Insertable filters
  • Spot filters


Thanks to the integrated reverse jet cleaning system, these filters can be operated 24 hours per day without interruption.

Products

c

CARM-GH cased filter

This is a centrally positioned filter with which one or more dust emission sources can be extracted simultaneously. The modular design of the filter offers maximum flexibility in terms of set-up, filtration area and air flow rates. The flow rates can vary from 1,000 m3/h to as high as 100,000 m3/h.

The separated dust is collected in a dust bucket/container positioned under the hopper, or discharged via a screw conveyor or rotary valve into a big bag, or via another disposal route.

CARM-V insertable filter

Insertable filters are built into product receivers, silos, mixers, hammer mills, crushers and receiving hoppers, among others. Installed in customized housings, they can also be used at transfer points in conveyor belt systems. The separated dust is returned into the product flow. CARM-V filters are of a modular design.

This offers maximum flexibility in terms of filtration area and air flow rate. The flow rates can vary from 1,000 m3/h to 30,000 m3/h.

Kastfilter CARM BFE

CARM BFE spot filter

An extremely compact filter that can be mounted at conveyor discharge points, chain conveyors and elevators. It can also be used as a silo venting filter. The separated dust is returned into the product flow. The air flow rates vary from 400 m3/h to 2,000 m3/h.

Why DCP dust filters?

Low compressed air consumption during cleaning

The needle-felt envelope filter bags slide over steel filter frames, which are fitted with specially shaped openings. The cleaned air flows through the openings into the clean air chamber, from where it is extracted to the outside air.

The filter elements are periodically cleaned by compressed air being injected against the direction of the air flow. During this compressed air injection, a large volume of additional ambient air is induced through the same openings – thanks to the resultant venturi effect. This creates a brief but powerful reversal of the airflow direction, which cleans the envelope filter bags. The venturi effect means that the volume of compressed air required is low.

Customization and quality

Thanks to modular construction and flexible production, each filter can be tailored exactly to your requirements. This allows us to supply customized products at standard prices. Our filters are recognized for their solid construction and excellent manufacturing quality. If required, the filters can be manufactured entirely in SS304 or SS316.

Suitable for ATEX zone 22 and explosive substances

Our dedusting filters, fans and rotary valves can, of course, be manufactured to comply with ATEX 114 (directive 2014/34EU) for use in zone 22. If explosive substances are extracted, the filters are reinforced to withstand a reduced explosive pressure of max. 0.5 bar (o). In addition, they are fitted with safety components such as explosion relief plates or flame arrestors, ATEX isolation valves in the inlet – and clean air duct, and a flame and pressure-resistant rotary valve.
