ABSTRACT:
A self-cleaning air filter includes a tubular housing and an annular filter cartridge removably and rotatably supported in the tubular housing. A removable cover at one end of the housing provides access to the housing for insertion and removal of the filter cartridge. A first rotary support for one end of the filter cartridge is mounted on the removable cover and includes a short shaft supported by the cover and a hub assembly rotatably mounted on the short shaft. The hub assembly is releasably secured to one end of the filter cartridge. A pair of successively smaller diameter tubular extensions are provided at the other end of the housing through which clean air passes outwardly from the filter. A second rotary support for the filter cartridge includes a turntable mounted inside of the housing by a tubular neck which is journaled inside of the first tubular extension. The turntable has a peripheral flange which snugly engages the other end of the filter cartridge with a friciton fit. An air nozzle having a narrow elongated slot is adjustably supported inside of the filter cartridge to direct air radially outwardly through the cartridge for back flushing same when the cartridge is rotated. The nozzle is biased toward the inside surface of the filter cartridge. A motor is drivingly connected with either of the first and second rotary supports for rotating the air filter cartridge.
