A filter backflushing system including either a pneumatically-driven piston or pneumatic accumulator for propelling a supply of a filtered backflushing fluid, contained in a backflushing fluid chamber, in a reverse direction through a filter element. The filter backflushing system provides a high intensity, substantially instantaneous, constant pressure backflushing flow which effectively removes clogging contaminants from the filter element.
