The discharge pipe is provided with a static pressure tap connected with a differential pressure gauge, besides including a Pitot tube connected with a micromanometer, a temperature sensor and an air damper. This unit consists of a centrifugal fan equipped with cylindrical suction and discharge ducts. Motor r.p.m. can vary continuously thanks to a digital inverter that also indicates the number of r.p.m. and the absorbed power. The suction duct is provided with a static pressure tap connected with a differential pressure gauge, besides including a temperature sensor and an air damper.

Training Program

This unit enables to deepen the following issues:

Determining the power absorbed by the motor versus r.p.m. and flow rate

Determining flow rate with Pitot tube

Checking the laws of similarity (rpm vs m/s, rpm2 vs mmH2O, etc…)

Plotting the characteristic curve of a fan at different r.p.m. values.
