This compact bench-top experimental unit familiarizes students with basic experimental characteristics of a centrifugal fan. It consists of an industrial centrifugal fan along-with pressure and temperature sensors on the inlet and outlet ducts. A controllable louvre allows to change the intake airflow.

Students can read the variable off the built-in display or can connect the unit to a computer (not supplied) for graphical visualization of the variables.

Rotor blade direction can also be reversed to observe the influence of direction of blades on the variables.
