Abstract
A fan includes a casing having an air inlet and an air outlet, an impeller housing located within the casing, an impeller located within the impeller housing for generating an air flow along a path extending from the air inlet to the air outlet through the impeller housing, a motor housing connected to the impeller housing, and a motor located within the motor housing for driving the impeller. A bellows support is provided for mounting the impeller housing within the casing. The bellows support is disposed on a seat connected to the casing. The bellows support extends about the impeller housing and forms a seal between the impeller housing and the casing.
Claims19
A fan comprising:
- a casing having an air inlet and an air outlet;
- an impeller housing located within and surrounded by the casing;
- an impeller located within the impeller housing for generating an air flow along a path extending from the air inlet to the air outlet through the impeller housing;
- a motor housing connected to the impeller housing;
- a motor located within the motor housing for driving the impeller;
- a bellows support of undulating shape for supporting the impeller housing within the casing, the bellows support being mounted on a seat connected to the casing, the bellows support extending about the impeller housing and forming a seal between an outer surface of the impeller housing and an inner surface of the casing;
- and
- a system for inhibiting rotation of the bellows support relative to the casing.
