It corresponds to the safety requirements for devices Welding fume class "W3" (high-alloy steels with alloy components > 30% Nickel-based alloy).If used as intended, the system can be used for the Recirculation mode used because the requirements for the Exceptions according to TRGS 560 are fulfilled. That special developed, dirt-dependent cleaning system ensures a good cleaning behavior of the filter cartridge, so that an optimal suction performance is guaranteed throughout the operation. The cleaned particles fall into a dust collection drawer from which they can then be disposed of. The powerful spiral fan ensures even with saturated Filter cartridges for a high volume flow. The filter media ----- A baffle serves as a pre-separator for coarse particles. The filter cartridge installed below (dust class M, degree of separation > 99%) filters the finest smoke and dust particles. The cartridge is factory coated which increases the service life. The extraction arm ----- The extraction arm can be moved with the 3 internal joints Position spring support slightly and is in the set position cantilevered. A throttle flap integrated in the extraction hood enables the Flow rate setting.
