The unit is part of an automated welding system. Areas of application for the unit are manual welding and automated welding/robot welding. During welding, harmful welding fumes are produced which are filtered and cleaned by the unit's internal filters.

The device can be used to extract fumes and dust when welding or cutting steel with an alloy content of nickel and chrome under 30%.

Two motors draw the welding fumes through the intake ports to the central section of the unit. When this occurs, the welding fumes are drawn through the filter membrane of the filter cartridges. The filter membranes trap the dirt particles. The cleaned air is then routed to the top section of the unit and returned to the environment via exhaust air grilles.

The device is equipped with two rotary nozzles, which with the help of a pulse of pressurized air, blow dirt and debris out of the filter membranes. The dirt particles are trapped in a dust collection bin.

The unit is equipped with an automatic start-stop feature. Used together with a connected clamp-on ammeter, the automatic start-stop feature makes it possible to switch the extractor on automatically when the welding process starts (automatic mode). Once the welding process begins, the device receives a signal from the current clamp and automatically starts the fume extraction process. Use of the automatic start/stop mechanism extends the service life of the device.

The following fume collection devices can be connected to the unit:
