Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder includes a first chamber, a second chamber, at least one inlet tube structured and configured to allow ambient air to enter the first chamber, at least one flow tube structured and configured to allow air to pass from the first chamber to the second chamber, and a blower structured and configured to produce a flow of air at positive pressure. The blower is positioned in the first chamber and structured and configured to receive air from the second chamber. The blower includes a housing structured and configured to sealingly separate air flow through an interior of the housing from the first chamber. The at least one inlet tube is axially spaced from the at least one flow tube.

Respiratory pressure therapy device

A blower includes a housing including an inlet and an outlet, a motor to drive a rotatable shaft, first and second impellers provided to the shaft, the first and second impellers each including a plurality of impeller blades, a first stationary component provided to the housing and including stator vanes downstream of the first impeller, and a second stationary component provided to the housing and including stator vanes downstream of the second impeller. A first set of stator vanes of the first stationary component is provided around the motor and are configured and arranged to direct airflow along the motor, to de-swirl the airflow and to decelerate air to increase pressure. A blower including a third impeller and third stationary component positioned above the first impeller is also described.
