Operation of Air Pump
Air enters through centrifugal filter. Rotating fan blade traverses across the chamber, forcing the air to the air outlet while new air enters in the rear of the blade. This air volume is now transferred by the second blade, etc. Each blade completes one pumping cycle per rotor revolution. Blade ends do not contact the walls of the housing, they may however, contact during the break-in period. Air pump and centrifugal filter are maintenance free. The air pump cannot be repaired, but must be replaced when inoperative. Pressure control valve may be exchanged.
