Stationary Welding Fume Filter
The SFS is a wall-mounted filter unit that provides filtration for use with
one extraction arm and fan. The SFS features a round filter cartridge.
This filter cartridge is provided with a precoat to extend the lifespan and
the efficiency of the filter.
The SFS is fitted with a RoboClean system for automatic sectionwise
cleaning of the filter cartridge by (externally supplied) compressed air.
The dust and dirt particles end up in the dust bin. The SFS comes with
an external pre filter (spark arrester) in a separate box. The SFS needs
to be connected to a control box.
