This a bench top unit for studying the centrifugal blower characteristics.

The unit consists of an industrial type centrifugal blower with a motor and advanced inverter, inlet and outlet ducts with flow straighteners, a damper, and measuring instruments according to BS 848 and ISO 1042. Extra blades are provided for comparison study.

Instruction manual is also included.

  • Inlet and discharge pressures vs blower speed.
  • Flow rate vs speed.
  • Blower input, output and efficiency.
  • Comparison of backward, radial, and forward blade impellers.
Blower rating at 2900 rpm:
 - Maximum flow rate (unchoked) 15 m3/min
 - Maximum head (fully choked) 150 mm. water
Inlet duct with flow straightener
Outlet duct with flow straightener and damper
Speed control Advanced inverter
Measuring instruments
 - Air flow rate Inlet orifice plate or Venturi nozzle with inclined water manometer
 - Differential pressures Twin inclined water manometers (one for air flow rate), 0-450 mm x 1 mm graduation, multiple slope 1:10, 1:5, 1:2 and 1:1
 - Blower speed and motor input power : Advanced inverter Advanced inverter
 - Temperature Thermometer
Accessories 2 extra impellers with radial and forward blade designs and barometer
Power supply 220 V, 1 Ph, 50 Hz. Other power supply is available on request.
