Zusammenfassung:	A ventilation system (100) for providing a flow of gas comprising: a housing (180) containing a blower (150); an intake tube (115) having an inlet portion and and outlet portion; an intake chamber (110) having an open end, a bottom, and protruding sidewall forming a cavity, wherein the open end of the intake chamber is positioned over the inlet portion of the intake tube; one or more apertures (125) provided in the bottom or protruding sidewall of the intake chamber, the one or more apertures being configured to receive ambient air drawn into the housing by the blower; and a plurality of attenuators (120, 170) disposed within the cavity of the intake chamber, the attenuators defining a tortuous air path between the one or more apertures and the inlet portion of the intake tube.
