HM 210 Characteristic variables of a radial fan

GUNT HM 210

The Radial Fan Experiment System allows for detailed study of the characteristic variables of a radial fan.

The system includes a radial fan with adjustable speed, controlled by a frequency converter. Flow rate is adjustable through an iris diaphragm or Venturi nozzle, with pressure measurements taken using a U-tube manometer, single tube manometer, and inclined tube manometer. The system digitally displays speed, torque, and electric power capacity. 

This equipment is ideal for educational purposes in fluid dynamics, focusing on fan performance under different operating conditions. This system is ideal for studying the key performance parameters of radial fans, including their torque, pressure differences, and airflow behavior in a controlled environment.
