- model - DV(S)...G
- Backward curved impellers made of plastic.
- model - DVE(S)...G
- Efficiency optimized and sound optimized backward curved impellers of the REVOLUTION series made of plastic.
- model - DVW(S)...G
- Efficiency optimized backward curved impellers made of aluminum.
Electrical connection
- up to size 225
- The motors are equipped with a built-on terminal box with easy access for electrical connection after removal of the rain cover.
- from size 250
- The electrical connection is possible over the mounted ON/OFF-switch.
- Type "open loop"
- In the “open loop” (standard) model, the speed is continuously provided by a 0-10V signal or a potentiometer (accessories).
- Type "closed loop"
- In the “closed loop” model, the pressure setpoint is continuously provided via a pre-wired potentiometer or a 0-10V signal. The pre-assembled pressure sensor has a display (Sizes 190-310 without display) with an adjustable pressure measurement range of (100 Pa, 300 Pa, 500 Pa, 1000 Pa).
