ABSTRACT:
A fan assembly (14) for ventilating an essentially closed chamber such as an inflatable storage chamber for a motor vehicle comprises a base plate (17) for mounting over an opening through a wall (13) of the chamber, the base plate defining an aperture (21) therethrough and an electrically-driven fan (28) being arranged to draw air from a first plenum (31) upstream of the fan and drive the drawn air into the chamber. An air treatment unit (25) is disposed over an opening through the base plate between the chamber and the first plenum (31). A first filter (22) is disposed in an opening between the first plenum (31) and the external atmosphere (35). In this way, air driven into the chamber by the fan (28) will be a mixture of air drawn from the external atmosphere through the first filter (22) and air drawn from the chamber through the air treatment unit (25) into the first plenum (31), to be recirculated into the chamber.
