A system for delivering a pressurized flow of breathable gas to a patient includes a patient interface configured to contact the patients head. The patient interface includes a frame, a cushion supported by the frame and configured to sealingly connect the patient interface to the patients face and form a chamber between the frame and the wearers face, and an inlet port in the frame to receive the pressurized flow of breathable gas. A flow generator is configured to generate the pressurized flow and is capable of creating a pressure of about 2-40 cm H20 in the chamber. A flow generator housing is provided to house the flow generator. The flow generator housing is mounted on the patient interface and configured to reduce the transmission of vibration and/or noise generated by the flow generator to the patient interface.
