Abstract: An air distribution system of a car wash air blower system is provided for directing air to a vehicle travelling along a predefined path using an air producer mounted on each side of the path for producing flowing air. Nozzle assemblies are attached to the distribution system at the ends of the predefined routes for directing air toward a vehicle travelling along the vehicle path. A pivoting hinge hinges a nozzle relative to a distribution duct. A first hinge section is pivotally secured to the second hinge section in a manner allowing rotation of the second hinge section about a defined axis of air travel. The two hinge sections are secured by a frame mounted in the air flow path to the hinge sections. A nozzle directs a stream of air toward the surface of a vehicle positioned adjacent to the nozzle. One nozzle embodiment includes a curved air distribution cell formed of a flexible webbing and having a generally triangular shape. An alternative embodiment is a nozzle having a cylindrical shape.

Abstract: An air distribution system of a car wash air blower system is provided for directing air to a vehicle travelling along a predefined path using an air producer mounted on each side of the path for producing flowing air. An air distribution system associated with each air producer directs air along a plurality of predefined routes from the air producer to a plurality of locations along the path. The predefined routes are substantially symmetrical about a vertical plane containing the vehicle path. Nozzle assemblies are attached to the distribution system at the ends of the predefined routes for directing air toward a vehicle travelling along the vehicle path. The air producer completely encloses a fan and drive motor. A pivoting hinge hinges a first section of a duct relative to a second section of a duct. The first hinge section is pivotally secured to the second hinge section in a manner allowing rotation of the second hinge section about a defined axis of air travel.
