Advanced Engine Filtration

Course: Half Day, .4 CEUs
Tad Jaroszczyk, Barry Verdegan, Jerry Liu – Instructors

The course includes five major modules: engine air filtration, engine crankcase ventilation filtration, engine fuel and oil filtration and diesel engine emission reduction.  The course will focus on application needs and requirements, filtration models, design principles, filter media including micro- and nano-fiber media, as well as, filter performance and evaluation techniques, as they apply to engine filtration.

The objective of this short course is to provide practical information for those engaged in the design, testing, application, and sales of filtration systems for engines.  The course is intended for both novices and experienced filtration professionals seeking to hone their skills in this rapidly evolving field of application and to learn about design trends in air, exhaust, fuel, lube and crankcase ventilation filtration for engines.
