Centrifugal Fan Demonstration Unit

Centrifugal Fan Demonstration Unit

The Advanced experimental unit provides the basic experiments to get to know the operating behavior and the most important characteristic variables of radial fans.
Radial fans are used to transport gases with non-excessive pressure differences.  
The medium is drawn in axially to the drive shaft of the radial fan and is deflected by 90° by the rotation of the rotor and discharged radially.
To demonstrate the effect of different blade shapes two rotors are included in the scope of delivery: one rotor with forward curved blades and one with backward curved blades.  
The rotors are easily interchangeable.
The experimental unit is fitted with sensors for pressure and temperature.  
The flow rate is determinate via differential pressure measurement on the intake nozzle.  
The microprocessor-based measuring technique is well protected in the housing.  
The measured values are transmitted directly to a PC via USB where they can be analyzed using the software included.
