Function principle
The side-channel compressor consists of a drive (motor) and a compressor part in
which an impeller rotates contact-free in the side-channel.
Side-channel compressors can be used as a vacuum pump or are used as the
compressor (observe Correct use of the equipment [
➙
7]).
As soon as the motor is switched on, conveyed media is suctioned via the gas in-
let (1).
When it enters the side-channel the conveyed media is accelerated in the direc-
tion of rotation by the blades of the rotating impeller (3).
The centrifugal force presses the conveyed media to the inner wall of the side-
channel (2). From there, the conveyed media is supplied to the impeller blades
again.
With every renewed entry of the conveyed media into the impeller, it gains kinetic
energy and the pressure increases.
The cross section of the side-channel is limited at the interrupter.
In this manner, the conveyed media is stripped from the impeller blades and ex-
pelled via the gas outlet (4).
