Abstract
A transverse fan assembly including a fan rotatably disposed in an air plenum for driving air through an inlet opening and forcing air from an outlet opening defined by the air plenum. The fan includes an elongated axis of rotation defined by a central hub. A plurality of elongated fan blades extend in an axial cylindrical pattern about the hub to define an open-center fan. The fan further includes two disk-shaped fan blade mounting members arranged toward opposite ends of the fan. Each blade mounting member is connected to and extends radially from the hub. The fan blades are connected to and driven by the blade mounting members whereby establishing an air flow through the inlet opening and from the outlet opening. Each fan blade mounting member is apertured to allow air to be drawn endwise and inwardly through the fan mounting members to the open center of the fan from whence the air is exhausted by the rotating fan blades in a manner eliminating end air effects and providing a substantially even flow of air from the outlet of the air plenum and along the length of the fan.
