Abstract:

A powered precleaner separates debris from atmospheric air through the use of a blower and a separation chamber. The chamber includes people are inlet orifice and at least two exit orifices, including an outlet orifice and an exit orifice containing at least one heat exchanger. The blower blows air and debris along an inner surface of the separation chamber and out of the outlet orifice. The outlet orifice is sized to allow large debris to exit the chamber. Sufficient backpressure is created to cause a predetermined amount of precleaned air to flow through the exit orifice containing the heat exchanger. A screen may be added to trap larger light debris and prevent it from flowing to and plugging the heat exchanger.
