Centrifugal Fan Demonstration Unit
Product Code : EL-FMLE-10651
Centrifugal Fan Demonstration Unit (code EL-FMLE-10651) is an experimental set-up for learning the operating behaviour and main characteristic variables of a radial fan, which draws gas in along its drive shaft and turns it through 90° to discharge it radially. A 110 W fan with a 3-phase AC motor and frequency converter runs at a nominal 2800 min-1, giving up to 480 m³/h and 300 Pa, and two interchangeable rotors with forward and backward curved blades are supplied.

What Is the Centrifugal Fan Demonstration Unit Used For?
Radial, or centrifugal, fans move gases against moderate pressure differences, and their performance is described by curves of pressure rise, power and efficiency plotted against flow rate. Students set the fan speed on the frequency converter and close the throttle valve in steps, while the software records the differential pressure, the flow from the intake nozzle, speed, temperature and electrical power at each point and works out hydraulic power and efficiency. Exchanging the forward curved rotor for the backward curved one and repeating the run shows how blade shape changes the fan characteristic.

Frequently Asked Questions
How does a radial fan move the gas?
Gas enters axially along the drive shaft, the spinning rotor deflects it by 90°, and it leaves radially. Radial fans are used to transport gases with non-excessive pressure differences.
Which rotors come with the unit?
Two rotors are included in the scope of delivery, one with forward curved blades and one with backward curved blades, and they can be interchanged to compare the two blade shapes.
What do the measuring ranges cover?
Differential pressure reads 0 to 1800 Pa, flow rate 0 to 1000 m³/h, temperature 0 to 100 °C, speed 0 to 3300 min-1 and electrical power consumption 0 to 250 W.
What is the rating of the fan itself?
The radial fan draws 110 W, has a nominal speed of 2800 min-1 and delivers a maximum volumetric flow rate of 480 m³/h at up to 300 Pa pressure difference.
How is the flow rate found?
Flow rate is determined from a differential pressure measurement on the intake nozzle, and the value goes with the other readings to a PC over USB for analysis in the software supplied.
