Abstract

A sub-housing received within a housing of an apparatus for supplying breathable gas, includes a gas flow path between a gas inlet and a gas outlet and an impeller in fluid communication between the gas inlet and the gas outlet. The impeller is structured and configured to be releasably engaged with a shaft associated with an electric motor that is disposed exterior to the housing, whereby rotation of the shaft causes rotation of the impeller.
