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 D_max = 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
