Impellers
Aluminium sheet impellers with backward curved blades are used. The impellers are mounted directly on the rotors of the external rotor motors
Electrical connection
Integrated motor protection is indicated via an alarm relay. In the “open loop” (standard) model, the speed is continuously provided by a 0-10V signal or a potentiometer (accessory).
Direction of rotation
The direction of rotation is clockwise as seen from the suction side.
