WIX® Filters’ New Air Filter For Mack Trucks Exceeds Original Equipment Filtration Performance

Tuesday, 22 January 2008

WIX Filters engineers have designed a new aftermarket air filter that outperforms the original equipment (OE) for Mack Truck applications. The new WIX 42808 increases filter capacity over the OE design by 25 percent and wet capacity/filter life by better than 14 percent, while equaling the efficiency of the OE filter.

The new WIX 42808 is the newest member of the WIX radial lip seal air filter family. It features WIX’s revolutionary design, developed in 2005, featuring polyurethane radial seals and metal end caps on the closed end. The design provides increased filter element strength, a stronger cross section of sealing material, greater media stabilization and capacity, and a handle that allows for easier handling by technicians. By including these elements in the design of the 42808, WIX has engineered a product that is unmatched in capacity, function and convenience.

“WIX continues to provide value to our customers by offering technically superior filtration products that outperform original equipment,” said Bill Stamey, heavy duty product engineering manager for WIX Filters. “And while we consistently deliver on performance, we know the little things, like the handle on the end cap, make installation and removal of what can be a 20-pound dirt-filled filter easier for technicians.”

The WIX 42808 differs in form from the OE design by eliminating the centering cone in the end cap. The WIX end cap ID fits within the housing lid draw, while the lid holds the filter down on the top end cap surface. The molded polyurethane radial seals improve sealing capability and fit.

In addition, the filter features six smooth, non-stringy, non-flaking hot melt stabilization beads, providing a strong cross section of material for increased media stabilization. This is achieved during manufacturing by applying the smooth hot melt stabilizing bead, without mechanical contact, with the hot melt bead. The bead is driven into the media and expanded metal with an air jet.

These processes give the WIX 42808 a clean appearance and even pleat spacing of the T-542 corrugated media.
