ABSTRACT:
A self cleaning gas filtration system for filtering contaminants from a flow of gas. A filter element is disposed within a housing and configured to receive a first flow of gas from an inlet in the housing. A pressurized gas source is fluidly coupled to at least one tube having a plurality of perforations. The perforations are configured to backflush the filter with a second flow of gas from the gas source. An outlet is configured to receive at least a portion of the second flow of gas.
