AIRSEP® Diesel Engine Retrofit Kits

Update your diesel for cleaner, greener operation

Rid your engine room of a messy oily film and upgrade your older diesel engine to the new standards of air filtration and crankcase fumes disposal found on new engines sold today. The Walker AIRSEP is the premiere closed crankcase system that incorporates three systems in one. The unit includes a washable high performance air filter, a crankcase fumes disposal feature, and an integrated air intake silencer, all in one compact package.

The AIRSEP delivers value, performance, and reliability. Once installed, system benefits include: Lower engine crankcase pressure that helps reduce the chance of oil seal leaks. No more noxious crankcase odors in your salon or living areas. High performance air filtration that helps your engine breath better for increased performance and fuel economy, and a built-in silencer that helps to reduce air intake noise improving passenger comfort.

The AIRSEP is the only system on the market that mounts directly on your turbo air inlet as a single unit directly in place of your stock air filter. Retrofit kits are available for all makes and models of diesel engines, including naturally aspirated engines, and the wide variety of configurations make the system flexible for any application. The AIRSEP has been factory installed by major diesel engine manufacturers worldwide since 1989, and popular kits for Caterpillar, Cummins, and Detroit Diesel are listed here.
