ABSTRACT:
The air blower unit includes a casing having a lower wall, and upper wall and two opposed side walls, which together define two open and opposed end faces of the same profile. The casing also includes a mounting frame, together with an air blower which is mounted within the casing and which comprises a blower rotor, a drive motor for the blower rotor, and two symmetrical half shells which are mated together to define a volute chamber in which the blower rotor and the motor are mounted.
This unit is readily adaptable to two different configurations, according to whether the vehicle in which it is to be installed is of the left hand drive or right hand drive type.
