A four stage filter system removes dust and gases from the aspirated air. As a first stage a cyclone dust separator with integrated filter cartridge is used. Next, the air is routed through a particle filter and two paired active carbon filters. Dependent on the selection of the active carbon filter different contaminants as well as the tear gases CN and CS can be absorbed.
The filtration system FSA 60 can be adapted to different tasks with a comprehensive range of accessories. It can be erected outdoors and indoors and in any vertical or horizontal position. The compact design also permits installation in a passenger car. The housing is made from stainless steel and therefore is suitable for outdoor use in most weather conditions.
