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.

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.

Measurement setup:

Measured between two steel plates

Steel plate:

225 mm x 225 mm

Intake nozzle:

D: 155 mm; R: 25 mm

Distance between bottom and top plate:

90 mm

Overlapping impeller / nozzle:
