Centrifugal Fan Demonstration Unit
A small-scale centrifugal fan demonstration unit, comprising of an inlet duct, the fan, an outlet duct and an adjustable aperture, all mounted on a stainless steel base.
Equipped with electronic measurement sensors for fan head pressure, flow-rate (via orifice plate) and air temperature.
Transparent cover plate on fan volute for visibility.
Supplied with two different, easily interchangeable impellers.
Capable of being linked to a PC (not supplied) via a USB interface console (an essential accessory), which does not require internal access to the computer. Also allows interfacing to other software packages.
Supplied with software providing full instructions for setting up, operating, calibrating and performing the teaching exercises. Facilities for logging, processing and displaying data graphically.
Offers a complete teaching package of coursework and laboratory investigation, complete with a student questions and answers session.
Measurement of constant-speed machine performance in terms of static total pressures, rotor speed and motor shaft power, as a function of inlet flow
