ABSTRACT:
A kitchen exhaust apparatus comprises a fan housing which includes a cylindrical portion and an extension which extends tangentially and contiguously from the cylindrical portion. A bottom wall extends across the cylindrical portion and the extension, which bottom wall defines an inlet port in the cylindrical portion. A portion of the bottom wall located in the extension is sloped upwardly in a direction away from the cylindrical portion. An outlet port is located above such sloped portion of the bottom wall. A motor driven centrifugal fan is arranged in the cylindrical portion above the inlet port to draw-in air and cause particles entrained in the air to travel into the extension and upwardly and downwardly along the sloped portion. Drain apertures are located in the bottom wall so as to lie along the path of travel of such particles to facilitate drainage thereof into a gathering tray mounted beneath the fan housing.
