Side Channel Ring blower
vertically, for air compressing or vacuum and application.
Ultra-quiet; Direct drive by low-noise motor and built-in silencer are used to reduce the noise produced by running blowers.
No oily odor, Environmental protection; The blade does not contact with any other parts when rotating, free of lubrication and ensuring blowers free from contamination.
High Quality; The high precision processing and testing equipment and technologies enable all parts to conform to the strictest quality requirements, with IP 55 protection and insulation class F and H, which greatly reduce many kinds of breakdown. Since the motor and blower are separated by bearing, foreign matters can be prevented from entering. To ensure the quality, each blower has been tested strictly before delivery besides 3C, CE and ISO certifications.
High Performance; High compression rate, Low temperature of bearing rotation, Long longevity of lubricant, Easy to maintain except blade, Liongoal high pressure blowers have no any parts move, highly reliable and almost maintenace-free. Besides, the unique precise outside bearing with excellent heat radiation is adopted to enable the above features.


The air between impeller blades speeds up rotation and the gases outside the pump body are pushed into side slot (through inlet), The gases are compressed upon entering side channel, and go back between impeller blades for another speeding-up rotation.
When air goes through blade and side slot along a spiry track, each blade increases its compressing and speeding-up level. As the blade rotates, the kinetic energy of gases is increased, which in turn increases the pressure of gases that go through the side channel.
When air arrives the connection between side slot and release flange (the side channel becomes narrow at the outlet), gases will be immediately extruded out of vanes and released from the pump body through silencer at the outlet.
