A PAP system adapted for treatment of respiratory disease or sleep disordered breathing includes a patient interface (10) to be secured to and sealed against a portion of a patient's face, in use. A flow generator is adapted to be connected to the patient's head by a portion (490) of a headgear (40). The flow generator includes a blower (50) adapted to provide pressurised breathable gas to a patient through the patient interface. The blower is at least partially vibrationally isolated from the patient's body by at least one dampening means (49,485). The dampening means is adapted to reduce the amount of transmitted vibration received by the patient.
