ABSTRACT:
An improvement to self-cleaning gas filters, gas filter-separators or gas filter-coalescer devices. The improvement reduces the waste of gas during a self-cleaning cycle by a series of mechanical refinements to the internal seals, by improving the manufacturing steps, and by considering gas waste if the internal elements are damaged, during the cleaning cycle, by controlling the reverse gas flow based on differential pressure across the elements that are being cleaned. Some of the improvements are field retrofitable to existing devices whereas other improvements can only be made to the present art during the manufacturing phase.
