This is a bench top set for studying industrial type axial flow fan characteristics.

The unit consists of a single stage variable pitch axial flow fan and motor, an advanced inverter, inlet and outlet ducts, and instruments for measurement of air flow rate, pressures, and temperature. The unit is on wheels.

Instruction manual is also included.

  • Flow rate vs pressure.
  • Fan input, output and efficiency.
  • Effect of speed on fan performance.
  • Effect of impeller pitch angle on fan performance.
  • Investigations of velocity distribution.
  • Effect of guide vane on fan performance (optional).
 - Diameter 380 mm
