When the blade of high pressure air blowers rotates, the wind vane causes gases to move forward and outward under centrifugal force, producing a series of spirally movements. 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 spirally 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.
