Device for continuous operation for low to medium amounts of smoke.

With the high-vacuum welding fume filters in the SRF SK series simultaneous extraction is possible at several points via a connected pipe system. The strong vacuum guarantees optimal suction even over longer distances. With a side channel compressor as a suction unit, the devices can also be used in continuous operation. SRF SK models are available in four performance levels. 

Your Benefits

  • Simultaneous extraction from up to eleven workstations possible
  • Rated for continuous duty operation
  • Low operating costs with cleanable long life cartridge filters
  • Low operation noise

Special Features

  • High vacuum welding fume filter with side channel blower for high suction power in several places
  • Filter cleaning with compressed air gun, pneumatic or pulse-jet cleaning system
  • Cleanable long life cartridge filters (Dust classification M)

Mobile installation

Mobile installation

Mobile dust extractors can be installed for single-location or central extraction in production halls.

Manual standard filter cleaning

Manual standard filter cleaning

Fast, effective filter cleaning with a hand-held compressed air pistol blows the filter lamellas clean inside and out. Smoke particles come loose from the filter material and fall into the filter housing's dust collection channel.

Fully automatic filter cleaning

Fully automatic filter cleaning

In automatic cleaning, the filter is cleared after the fan stops. On devices with an IFA test certificate, an acoustic signal indicates the need for filter cleaning.

Pulse-jet filter cleaning

Pulse-jet filter cleaning

Pulse-jet cleaning clears the filter cartridges from the inside out (clean gas side). This loosens dust stuck to the exterior of the cartridges, and it falls into the collection container. The filter cartridges are automatically cleanes individually. Pulse-jet cleaning allows filter cleaning during suction operation with no need to shut off the extractor.
