New Bypass Spin Filter

Luber-Finer has developed a new bypass spin filter named Zgard that is designed to boost the removal of soot and corrosive acids from the motor oil used in Exhaust Gas Recirculation (EGR) equipped engines.

Luber-Finer has developed a new bypass spin filter named Zgard that is designed to boost the removal of soot and corrosive acids from the motor oil used in Exhaust Gas Recirculation (EGR) equipped engines.

Unveiled at the recent Mid-America Trucking Show, Zgard works in addition to the existing full-flow filter on EGR engines, stressed Brent Birch, Luber-Finer’s engineering lab manager.

“Handling 12 to 15 gallons per minute of oil flow doesn’t give the primary filter time to take out all the soot EGR engines generate,” he said. “By using a bypass filter, fleets have a chance to better manage that situation and possibly increase oil drain intervals.”

Birch said Zgard is the result of an 18-month development program that began in August 2002. “It’s no secret that bypass filters work to help remove more soot from the engine oil – but the key with Zgard is that it removes both soot and acids, protecting the engine from corrosion that could occur from the formation of sulfuric acids as a result of the EGR process.”
