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
• Measurement of fan efficiency and estimation of impeller power efficiency
• Measurement of performance at constant speeds
• Introduction to similarity laws for scale-up
• Comparison of student calculations with computer results
