Centrifugal Fan Demonstration Unit

Specification of 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.
