Cyclotron Separator combines a long tapered cone, a high velocity inlet, and a large internal helix to easily separate from the air stream all moderate size particles, such as saw dust chips and particles from metal grinding. The Cyclotron fans are positioned on the clean air side of the cyclone and are direct drive for low maintenance. In addition, the fans have backward inclined blower wheels for high efficiency and low noise operation. Optional Safety after Filters ensures that even the smallest particles are captured.
