The fume extraction unit WFE 2S is easy to install and operate. It is designed as a smaller, central system and is supplied complete with flexible hose, arm, and bracket, ready for installation. A powerful, maintenance-free pump provides continuous fume extraction at a maximum air extraction rate of 230 m3/h. A built-in microprocessor controls the adjustable pump speed, avoiding unnecessary waste of suction power and saving energy. To optimize the degree of pollutant separation, the WFE 2S can be modified with filters for different applications.
