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.
