PROFI 47.1 is equipped with two longlife, three-stage, by-pass, ECO motors by Ametek, which allows the machine to achieve maximum performance level. 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 47.1 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 120 m with no more than 24 suction sockets. The vacuum cleaner is fitted with a universal piping connection and exhaust systems (on either side of the machine).
