The Centrifugal Fan Demonstration Unit has been developed for the study of the characteristics of a centrifugal fan. The unit is equipped with 2 different types of impellers; (forward and backward blades), which can be easily interchanged. The direction of the rotation can be changed using the 3-position command control. Vertical and inclined gauges allow a correct reading of the pressure. The inverter allows the speed to be varied, while observing the electrical power through the power meter. A Pitot tube allows the measurement of the air velocity at any point of the tube, and the measurements can be obtained from the digital display which is provided.
