ABSTRACT:
A disposable filter bag insert for use in a filter canister assembly that comprises a rigid ring of diameter to overlie a shoulder on the canister and be sealingly captured between the canister base and top. A filter stock of sheet stock construction is suspended from the ring and has a lock stitch extending along the bottom and one side edge thereof. A section of oil-adsorbent material is likewise suspended from the ring, but covers less than the entire surface area of the sock, such that fluid flow through the sock continues even if the oil-adsorbent material becomes clogged. The sock lock stitch is specially contoured where it is looped over the ring for enhanced sealing capture between the canister top and base.
