Side-channel blower units. Systems designed to take in dust resulting from sanding primer and fillers during surface treatment. Features a double cartridge filtering system: the first cartridge holds most of the dust and is cleaned by a timed pneumatic rotary nozzle; while the second cartridge (Hepa with build-up) holds the finer impurities that are still in the air flow. 

This product is specifically designed for firms that do not have a well-defined sanding area or in case it is not possible to install a centralised dust suction system. 

Dust is taken in and conveyed to a nylon bag which is very easy to remove. The machine features a device for real-time check of the Hepa cartridge efficiency. As option, a two-drawer module is available, for installation on exhauster top part.
