Three layers of progressively finer mesh synthetic media between 100% polyurethane top and base, this high flow, oil-free conical performance filter provides maximum convenience and easy maintenance with perfect airflow. Also is washable and reusable for multiple cleanings, the tall open evenly spaced pleats provide excellent dust holding capacity for longer service cycles between cleanings. Pliable polyurethane flange with integrated bumps insures a tight no leak seal over the life of the filter.
