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.
a.) Operation condition:
2.650 1/min at free air flow Frequency: 50 Hz
Max. free-air flow (∆p = 0 / = max.) 152,0 m3/h
Max. static pressure (∆p = max. / =0) 70 Pa
b.) Operation condition:
3.100 1/min at free air flow Frequency: 60 Hz
