Fan test rig

There are 3 permanent fan test rigs at the Institute of Fluid Machinery:
KA1 - Test rig for mid size and big fans
- Maximum volume flow V <= 7 m3/s = 25200 m3/h
- Input power auxiliary fan 20 kW
- Max. Diameter of fan under test Dmax = 700 mm
- Determination of flow rate: Belmouth nozzle
KA2 - Aero-Acoustic test rig for mid size and big fans
- Maximum volume flow V <= 3 m3/s = 10800 m3/h
- Simultaneous Aero-Acoustic measurement using "reverberation room"-method
- Determination of flow rate: Belmouth nozzle
KA3 - Test rig for small fans
- Maximum volume flow V <= 0,2 m3/s = 720 m3/h
- Determination of flow rate: Orifice plate
