Manufactured from 100% synthetic fibers and containing no fiberglass, this 3-layer polyester cube air filter provides high efficiency and long service life. The first layer acts as a high-porosity impingement filter and the third acts as a durable strainer to prevent unloading or streaming. A non-migrating tackifier between the second and third laminates assures positive filter-cake build up. The self-sealing, friction-fit frame can often eliminate the need for extra mounting hardware, while its heat-sealed laminated construction eliminates fiber break-off, and the media is easy to handle with bare hands.
These multipocket bag filters are self-sealing. The media construction is a multilayered gradient density structure designed to maximize paint collection and retention. The downstream layer also consists of a high-efficiency synthetic media.
