摘要: A filter element includes first and second ends, an extension of filter media, an outer liner, an inner liner, and a sealing ring. The first end cap consists essentially of a foamed polyurethane having an as molded density of about 14-22 pounds per cubic foot. The sealing ring extends outwardly only from the outer surface of the first end cap. The sealing ring is a molded part of the first end cap and consists essentially of foamed polyurethane having an as molded density of about 14-22 pounds per cubic foot. The sealing ring has an axially directed top edge, first and second sidewall portions, and a base. The first and second sidewall portions are immediately adjacent to and angled from the top edge of the sealing ring.

摘要: An air filter element includes structure for supporting a secondary air filter element mounted within it, such as a safety element. In certain arrangements, the air filter element includes a media pack having first and second ends and defining an open filter interior. A first open end cap is positioned on the media pack first end. A second closed end cap is positioned on the media pack second end. The spacer construction has attachment structure and positioning structure. The attachment structure secures the spacer arrangement within the open filter interior, and the positioning structure extends from the attachment structure. In one illustrated embodiment, the spacer construction includes an insert embedded within the second closed end cap. In one illustration, the insert has a circular disk with feet and a centrally extending post with a fin arrangement.
