3.4 Aerodynamics
Measurement
conditions:
Measured with a double chamber intake rig acc. to DIN EN ISO 5801.
Normal air density = 1,2 kg/m3; Temperature 23°C +/ - 3°C;
In the intake and outlet area should not be any solid obstruction within 0,5 m. Motor shaft
horizontal.
The information is only valid under the specified test conditions and may be changed by the
installation conditions. If there are deviations from the standard test conditions, the
characteristic values must be checked under the installed conditions. Power consumption of
the fan motor when operating at normal voltage is shown. Depending on the operating
conditions of the application, the power input may be higher.
a.) Operation condition:
5.000 1/min at free air flow
Max. free-air flow (∆p = 0 / = max.) 270 m3/h
Max. static pressure (∆p = max. / =0) 270 Pa
