Mobile welding fume filters for a wide range of applications.

Welding and soldering fumes are filtered at 99.9% efficiency, and then routed back into the work area. Thanks to the high air volume flow even larger clouds of fumes can be easily extracted. The cleanable permanent filter cartridges ensure low operating costs in the long term. The more powerful version SRF K-15 comes into its own when there are large amounts of smoke and when extraction is required at two workstations simultaneously.

Your Benefits

  • High performance smoke capture at two extracion locations
  • Mobile for versatile use and suitable for continuous duty applications
  • Compact and user friendly design
  • Low operating costs through cleanable cartridge filters
  • Easy disposal of the collected dust

Special Features

  • Filter cleaning with compressed air gun (manually) or fully automatic
  • 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.

Manual rotation filter cleaning

Manual rotation filter cleaning

A compressed air connection on the hand-operated rotation nozzle ensures that the filter lamellas are blown uniformly clean.

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.

Tested Quality

The welding fume filters in the SRF K-series are optionally available with the IFA test mark W2 and W3 for the extraction of welding fumes from high-alloy steels.

Special guidelines apply when welding stainlees steel. Depending on how high the chromium/nickel content of the stainless steel is, devices with an IFA W3 test certificate are needed if air is recirculated.
