HVAB 軸流ファン指導用演習装置

The Axial Fan Teaching Unit, "HVAB", allows the observation, the study and the working process analysis of an axial-flow fan.

The main element of this unit is a variable speed centrifugal fan, which is measured through a speed sensor, and a wattmeter determines the power consumed by the fan. The main tube of the unit is transparent. The air flow can be regulated through an adjustable oriffice at the inlet of the duct. It also has an oriffice plate for the calculation of the air flow with a slanted tube manometer.

There are also humidity, pressure and temperature measurements to know the inlet air conditions.

The unit is supplied with an electronic console with a speed variator to modify the speed of the axial fan, a speed sensor connector, a digital display for the speed sensor, and a digital display for the fan power measurement.
