Side channel blower operating Principle
The gas is taken in through the inlet
(1). As it enters the side channel
（2）, therotating impellor
(3 )imparts velocity to the gas in the directionof rotation Centrifugal force n the melor blades accelerates the gas outward and the pressure increases.
Every rotation adds kinetic energy.resulting in further increase of pressure along the side channel. The side channel narrows at the rotor, sweeping the gas off the impellor bladesand discharging t though the outlet silencer
(4)where it exits the pump.
The mpeler is mounted directly on the motor rotor is completely noncontact compression. Maximum diferential pressure, the pump bearings installed in the compression chamber, so even work canensuremaximum reliability of the machine.
