With five layers of progressive cotton gauze media and two layers of synthetic media between a 100% polyurethane top and base, this high flow conical performance filter provides maximum protection. Washable and reusable for multiple cleanings, the tall open evenly spaced pleats provide excellent dust holding capacity for longer service cycle between cleanings. A pliable polyurethane flange with integrated bumps insures a tight leak-free seal over the life of the filter.
