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.
• Equipped 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).
• Supplied 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

An 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 measured.
