Abstract: A blower assembly for an automatic car wash is provided. The blower assembly includes a housing, an impeller, a fan motor, an oscillation motor and an oscillation linkage assembly. The impeller is rotatively disposed in the housing. The housing includes an egress spout. The fan motor is rigidly connected to the housing. The linkage assembly mechanically relates the oscillation motor to the fan motor and housing and oscillates both. In the preferred embodiment, the motor and housing are rotatably supported on both axial sides of the motor and the motor shaft and motor housing drive substantially the same axis of rotation.
