The air flow and sound level of the centrifugal fans
without external housing depend on their individual
installation conditions.
The stated air flow and sound 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 impeller.
Speed control range from 800 rpm
-1
at 7% PWM up to nominal speed at > 90% PWM. Standstill at 0% PWM,
maximum speed if control cable is interrupted.
The specific service life is valid when an external capacitor is wired between the positive and negative wires.
Please note the wiring suggestion.
