ABSTRACT:
A dual port blowing device for drying a vehicle includes a centrifugal fan powered by a blower motor. The centrifugal fan is rotated upon the motor shaft and surrounded by a housing having a first outlet nozzle for discharging air toward the rear end of the vehicle, and including a second outlet nozzle for discharging air toward the front end of the vehicle. A pivoting damper moves between a first position for sending discharged air through the first outlet nozzle, and a second position for sending discharged air through the second outlet nozzle. An actuator selectively pivots the damper between its first and second positions. The actuator includes a hydraulic cylinder and piston for pivoting the damper. Control circuitry determines when the rear of the vehicle is proximate to the dual port blowing device, and operates the hydraulic cylinder to move the damper from its first position to its second position.
