Walker Engineering has been a leading innovator in marine air filtration technology for over 25 years. In 1988, the company introduced the first AIRSEP system for marine diesel engines, which quickly became the industry standard for air filtration.

The AIRSEP system was developed to address a common problem in marine diesel engines - the accumulation of soot and other contaminants in the engine's air intake system and a buildup of crankcase vapors. This buildup can reduce engine performance, increase maintenance requirements, and even cause engine damage over time.

One major area of concern was the release of crankcase vapors into the atmosphere. As emissions regulations became more stringent, diesel engine manufacturers started to look for ways to reduce the amount of pollutants released into the environment. 

Crankcase vapors are generated by the engine's internal combustion process and can contain a variety of harmful pollutants, including hydrocarbons, particulate matter, and nitrogen oxides. To address this issue, Walker Engineering developed a CCV system that works in conjunction with engine air filtration.

The AIRSEP system solves this problem by separating the air and oil vapor that are drawn into the engine's air intake system. The system coalesces the crankcase vapors by separating out the oil vapor and other contaminants and directing them to a separate chamber using a patented design.

The Airsep system is designed to provide  comprehensive air filtration and crankcase ventilation for marine diesel engines. With a focus on quality, performance, and environmental responsibility, Walker Engineering continues to innovate and refine its AIRSEP and CCV systems to meet the evolving needs of the marine industry. 

The system also helps to reduce oil consumption, improve engine performance, and extend engine life by reducing the amount of harmful contaminants that enter the engine's air intake system.

Over the years, Walker Engineering has continued to innovate and refine the AIRSEP system, introducing new features and improvements to enhance performance, efficiency, and reliability. Today, the company offers a wide range of AIRSEP systems and components to meet the needs of virtually any marine diesel engine.

With a long history of innovation and a commitment to quality, Walker Engineering's AIRSEP systems continue to be the industry standard for marine air filtration working for a cleaner future.
