3.3 Aerodynamics
Measurement
conditions:
Measured in suction side throttled double-chamber test rig acc. DIN EN ISO 5801 and using a
dedicated ebmpapst-setup for cross flow blowers.
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.
Operation condition: 4.450 1/min at free air flow
Max. free-air flow (∆p = 0 / 251658240
= max.) 71,0 m3/h
max. allowable operation point on the fan chart
volumetric flow rate 52,0 m3/h
pressure (∆p) 25 Pa
