The side channel blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (and fuel tank), drip nozzle.The blower operates eccentrically by the rotor offset in the cylinder, and causes the
volume change between the blades in the rotor slot to inhale, compress and expel air.In operation, the pressure difference of the blower is used to automatically send the lubrication to the drip nozzle and drop it into the cylinder to reduce friction and noise. At the same time, the air in the cylinder can be kept from flowing back. 

The side channel blower also called air blower, regenerative blower or ring blower, gas blower, air pump, it have many name just because the different culture and customs in different areas.It simply explain that it is a blower support the air and pressure in the vacuum and pressure line.



  1. The Impeller inside the air blower operates without friction during running, no need lubrication, and the air outside is oil free,It is an ideal pneumatic conveying source for chemical, food and other industries.


2. The blower is a volume operated air blower. When used, the air flow become little while the pressure going higher. And the air flow will also change varies with the RPM. Therefore, the choice of pressure is wide, air the air flow can get through the speed.


3. The speed of the side channel blower is relatively high, and the gap between the rotor and the rotor, the rotor and the body is small, so that leakage is small and the volumetric efficiency is high.


4. The structure of the side channel blower determines that its mechanical friction loss is very small. Because only the bearing and gear pair have mechanical contact on the material selection, the rotor, casing and gear ring have sufficient mechanical strength. Safe operation and long service life are a major feature of side channel blower products.


5. The rotor of the regenerative blower is checked by static and dynamic balance. The finished product runs smoothly and the vibration is extremely small.
