Application
The RAK-1 and RAK-2 is a suitable solution for cleaning the
air from welding fumes forming at the mobile and stationary
welding posts. The polluted air is captured through
the ERGO extraction arm attached to the device. After the
filtering process, the air is recirculated back to the room.
Due to the silent work, it is possible to put the filtering unit
close to the workplace.
