COMPACT LOW NOISE EFFICIENT BLOWER FOR CPAP DEVICES

摘要

A blower (100) for providing a supply of air at positive pressure in the range of approximately 2cmH2O to 30cmH20 includes a motor (140), at least one impeller (150, 152, 154), and a stationary component (170, 172, 174, 180, 182, 184, 190, 192). The stationary component (170, 172, 174, 180, 182, 184, 190, 192) includes an inlet (130) and an outlet (120). The motor (140), the impeller (150, 152, 154), the inlet (130) and outlet (120) are co-axial.
