Axial Fan Demonstration Unit .
Axial Fan Demonstration Unit
- A small-scale axial
fan demonstration unit, comprising of an inlet duct, the fan, an outlet
duct and an adjustable aperture, all mounted on a stainless steel base.
with electronic measurement sensors for fan head pressure, flow-rate
(via orifice plate), fan speed and air temperature.
- Transparent ducts give visibility of the fan in operation.
- Capable of being linked to a PC (not supplied) via a dedicated interface console (an essential accessory).
with software providing full instructions for setting up, operating,
calibrating and performing the teaching exercises. Facilities for
logging, processing and displaying data graphically.
- Full theoretical back-up together with a student questions and answers session.
Description of Axial Fan Demonstration Unit
axial fan, mounted on a stainless steel plinth. Transparent air inlet
and air outlet ducts allow the fan construction to be clearly observed. A
manually operated adjustable aperture allows the air flow rate to be
varied. A calibrated orifice plate is used on the discharge to measure
the air flow rate. Electronic sensors measure the pressure head
developed across the fan, the pressure across the orifice plate (and
hence the flow rate), the rotational speed of the fan and the air
temperature. The fan speed is controlled by modulated dc supply,
complete with current sensing to allow the power drawn by the fan to be
