Side-channel blower units, for centralised dust extraction system. Designed to take in dust resulting from sanding primer and fillers during surface treatment. They feature a cartridge filter, cleaned by a timed pneumatic rotary nozzle.

Dust is taken in and conveyed to a nylon bag which is very easy to remove so that collecting the dust is simple. The machine features a device for real-time check of the cartridge efficiency. Can be disassembled in two main units (suction unit and filtering unit).
