Stationary filters


The SFS is a wall-mounted welding fume extractor with a self-cleaning filter. It is designed for medium dry welding applications.

  • Self-cleaning filter
  • Long filter life
  • Heavy-duty external spark arrester for enhanced safety and easy maintenance

The SFS is a stationary unit with self-cleaning filter

Recommended for

  • Medium to medium-heavy applications
  • Professional manual welding
  • Intermittent semi-automatic welding
  • Robotic welding

The SFS is a wall-mounted self-cleaning filter for welding fume extraction system up to 1200 m3/h. Typical uses are small extraction hoods or arms. The SFS uses the patented RoboClean for automatic cleaning of the filter.


  • Long filter life
  • Heavy-duty external spark arrester for enhanced safety and easy maintenance
  • Roboclean automatic sectionwise cleaning of the filter cartridge with compressed air

This popular filter unit has a fan waiting!

The SFS can be attached on the following extraction fans:

  • FAN-28; Welding processes with light to medium intensity. Used for extraction arms with a length of 2 - 4 m
  • FAN-42; Welding processes with medium to medium-high intensity. Used for extraction arms with a length of 3 - 8 m (in combination with an extension crane)

A stationary filter unit alone, won't do much!

Combine the SFS with one of the following extraction arms:

  • SFS with Flex
    For low to standard number of position changes. Designed for all kinds of dry welding activities, like MIG/MAG, TIG, stick, electrode and spot welding.
  • SFS with UltraFlex
    For standard to high number of position changes. Designed for applications that generate oily welding fumes.
  • SFS with UltraFlex (low ceiling)
    For standard to high number of position changes and low ceilings. Designed for applications that generate oily welding fumes.
  • SFS with T-Flex (telescopic arm)
    Designed for standard welding applications at workbenches and in small, fixed working places. 
  • SFS with T-Flex (counterweight)
    Telescopic extraction arm. Designed for standard welding applications at workbenches and in small, fixed working places. More precise positioning due to the counterweight.

Go above and beyond and extend the reach of your extraction arm

NEC extension crane: Extend the reach of your Flex and UltraFlex extraction arms with 2 or 4 m to a maximum of 8 m
