The WallMaster filter system from Kemper is a stationary unit with a large filter surface. The unit is suitable for filtering medium quantities of welding fumes and dust at up to two workplaces simultaneously. The filter surface of 42 sq. m is decisive in this respect. The system effectively separates ultra-fine particles with a size of less than 0.1 micron to a degree of more than 99.5 percent. The unit can be mounted on the hall wall, a pillar or a separately available stand.
