Abstract
A method for controlling an automatic stall-prevention of a rotation-speed-regulated centrifugal fan. A control automatics is controlled by an automation system of the process wherein, the control automatics stalling is detected from a function of the electric current, voltage and frequency going to the motor of the centrifugal fan.
