A first vibration isolator such as a plastic saddle is provided in the mounting arrangement for the air moving device for absorbing vibrations and a second vibration isolator in the form of a flexible connector is positioned between the air moving device and the second air duct passage. A third vibration isolator in a mounting arrangement for the discharge muffler may also be used.
