Axial Fan Demonstration Unit
Product Code : EL-FMLE-10647
Axial Fan Demonstration Unit (code EL-FMLE-10647) is a small-scale teaching unit used to demonstrate an axial fan, which produces gas flow parallel to its axis of rotation through momentum changes imparted across its rotary blades. The fan sits between transparent inlet and outlet ducts on a stainless steel base, with an adjustable aperture to vary the airflow and a calibrated orifice plate on the discharge. It gives up to 38 l/s typical flow and 0.06 kPa maximum head at up to 2,700 rpm from a 5 W motor.

What Is the Axial Fan Demonstration Unit Used For?
An axial fan moves air along the line of its shaft, and comparing the head, flow and power it gives at different operating points shows why this type suits large flows at low pressure. Students run the fan from the modulated DC supply and open or close the adjustable aperture to change the airflow, watching the blades through the clear ducts. The sensors pick up the head across the fan, the orifice plate pressure difference that gives the flow rate, the fan speed, the air temperature and the current drawn, and through the USB interface console the readings are logged on a PC and shown as graphs.
What to Specify When Ordering
- Quantity — the number of fan units required.
- USB interface console — the console used to link the unit to a PC, listed as an essential accessory.
Frequently Asked Questions
What does the unit show about axial fans?
It shows how an axial fan produces gas flow parallel to its axis of rotation through momentum changes across the rotary blades, a type more suited to higher flows at lower delivery pressures than a centrifugal fan.
How is the airflow rate varied and measured?
A manually operated adjustable aperture varies the airflow, and a calibrated orifice plate on the discharge measures it; an electronic sensor reads the pressure across the plate to give the flow rate.
Which quantities do the sensors record?
Electronic sensors measure the pressure head developed across the fan, the pressure across the orifice plate, the rotational speed of the fan and the air temperature, while current sensing gives the power drawn.
What are the performance limits?
The maximum flow rate is 38 l/s typical, the maximum head is 0.06 kPa and the maximum fan speed is 2,700 rpm, with a motor power rating of 5 W.
Can the unit be connected to a computer?
Yes. It links to a PC through a USB interface console, an essential accessory that needs no internal access to the computer. The software logs, processes and plots the data and can interface with other packages.
How large and heavy is it?
The unit measures 850 × 450 × 950 mm (L × W × H) and weighs 90 kg, with the fan and ducts mounted on a stainless steel plinth.
