Patent attributes
A self-cleaning water filter system for removing particulate matter from water by producing scouring effect which pulls debris or particles off from a filter element when a fluid flow is produced across the filter element. The self-cleaning water filter system has a filter housing having an upper portion, a lower portion, and an internal cavity. A water inlet tube, an exit tube and a water supply line are adapted to be connected to the filter housing. The filter element is positioned within the filter housing and can have a cylindrical or rectangular configuration. A pressure vessel is in fluid communication with the internal cavity of the filter housing. A pressurizable flexible chamber adapted to expand and contract due to the pressure in the filter housing is positioned inside the pressure vessel. At least one perforated flow tube is positioned in the filter housing adjacent to the filter element and in fluid communication with the pressure vessel.
