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.
The Experimental Unit Provides The Basic Experiments To Get To Know The Operating Behaviour And The Most Important Characteristic Variables Of Radial Fans.
It Features A Radial Fan With Variable Speed Via A Frequency Converter, An Intake Pipe And A Delivery Pipe. The Transparent Intake Pipe Is Fitted With Guide Plates For Flow Guidance And With A Flow Straightener To Calm The Air. This Enables Precise Measurements Even With Heavily Reduced Operation. The Air Flow Is Adjusted By A Throttle Valve At The End Of The Delivery Pipe.
