Beschreibung
Zusammenfassung:	A gas delivery system that includes a housing and a flow generator that includes a blower assembly and an isolation assembly for coupling the flow generator to the housing. The isolation assembly includes at least one elastomeric isolation member having first and second portions, and the blower assembly is coupled to the isolation assembly through the at least one elastomeric isolation member. The first portion is able to shear in a first direction and the second portion is able to shear in a second direction generally perpendicular to the first direction to permit the blower assembly to move relative to the housing in three dimensions. Also, a gas delivery system that includes a housing and a flow generator provided within the housing, wherein the gas delivery system generates no more than about 30 or 35 dB(A) of noise regardless of the physical orientation of the housing.
