WIX Filters Awarded Two Patents for Technological Innovations

WIX Filters recently received two U.S. patents for advancements in filtration technology. U.S. patent No. 7,041,158, issued for a pre-molded air filter end cap and method of manufacturing an air filter, protects an invention that can lower manufacturing costs and improve filter reliability and sealing characteristics. Although they may be used in any filter system, the patented end caps are designed primarily for use on air filters in heavy-duty applications such as power generators, stationary engines, earth movers and over the road trucks.

GASTONIA, NC — WIX Filters recently received two U.S. patents for advancements in filtration technology.

U.S. patent No. 7,041,158, issued for a pre-molded air filter end cap and method of manufacturing an air filter, protects an invention that can lower manufacturing costs and improve filter reliability and sealing characteristics. Although they may be used in any filter system, the patented end caps are designed primarily for use on air filters in heavy-duty applications such as power generators, stationary engines, earth movers and over the road trucks.

Similarly, U.S. patent No. 7,001,440 was issued for a fluid filter assembly with a fin array that can increase filter media life and capacity while reducing the total space consumed by the media. Designed for – but not limited to – use in filtration for internal combustion engines, the invention features annular filter elements with fins that encourage mixing of contaminated inlet air to increase capacity and efficiency.

WIX has a longstanding history of manufacturing innovation and excellence. In the past two years alone, WIX Filters has earned a total of 12 U.S. patents for engineering advancements in heavy-duty filtration. Many of the technologies protected by these patents have been incorporated into WIX products, including a new one-part molded self-venting valve for spin-on fuel/water separator filters that reduces fuel spillage and water drain times (WIX 33406), extended drain spin-on oil filters that employ Spin-Flow technology to increase filter life and oil change intervals (WIX 57745XD), and heavy duty air filters with soft polyurethane sealing ends and a metal end cap/handle on the closed end to reduce installation and removal times.

Other examples of WIX’s achievements include the revolutionary spin-on oil filter. Patented by WIX in 1954, today the spin-on oil filter is installed at the factory as standard on most automobiles.
