The SFD is a wall-mounted filter unit for welding fume extractions systems. Normally used for light-duty or maintenance applications.

  • Long filter life
  • Large internal spark arrester
  • Full filter indicator

The SFD is a stationary filter unit with disposable filter

Recommended for

  • Light application with occasional welding
  • Repair shops
  • Welding schools

The SFD is a wall-mounted filter unit for welding fume extractions systems up to 1250 m3/h. The filter has a disposable filter, making it suitable for occasional and/or light welding applications. The filter is treated with pre-coat to enhance life span and filter efficiency. The SFD requires no electricity.


  • Long filter life
  • Large internal spark arrester
  • Full filter indicator

This popular filter unit has a fan waiting!

The SFD can be attached on the following extraction fans:

  • FAN-28
    Used on extraction arms with a length up until 4 m
  • FAN-42
    Stronger fan used on extended extraction arms due to the longer length (more than 4 m)

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

Combine the SFD with one of the following extraction arms:

  • 1 or 2 Flex arm(s)
    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.  
  • 1 or 2 UltraFlex arm(s)
    For standard to high number of position changes. Designed for applications that generate oily welding fumes.
  • 1 or 2 UltraFlex arm(s) for low ceilings
    For standard to high number of position changes and low ceilings. Designed for applications that generate oily welding fumes.
  • 1 or 2 T-Flex arm(s)
    Telescopic extraction arm. Designed for standard welding applications at workbenches and in small, fixed working places.

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
