PROFI 44 is equipped with a longlife, three-stage, by-pass, ECO motor by Ametek. The machine is designed to filter the air on two levels. The first is a cyclone separator, which uses centrifugal force to accumulate dirt on the bottom of the tank. The second level of filtration is a self-cleaning, PTFE-coated, fabric filter. PROFI 44 might also be used with a synthetic bag as another filter, a solution that makes emptying the tank easy and hygenic. The maximum piping length for this machine is 50 m with no more than 10 suction sockets. The vacuum cleaner is fitted with a universal piping connection and exhaust systems (on either side of the machine).
