Speed control range from 800 rpm at 7 % PWM up to nominal speed at > 90 % PWM. Standstill at 0 % PWM,
standstill if control cable is interrupted.
The specific service life is valid when an external capacitor is wired between the plus and minus wires.
Please note the wiring suggestion.

The air flow and noise level of the centrifugal fans without
external housing depend on their individual installation
conditions. The stated air flow and noise level were recorded
under the following measurement parameters:
Centrifugal fan mounted on a foundation plate 140 x 140 mm.
Cover plate 140 x 140 mm, with an air inlet opening Ø 94,4 mm,
arranged concentrically to the fan impeller.
