Walker AIRSEP®

Walker Engineering – For a Cleaner Future

Optimizing Performance & Reducing Emissions

Walker Engineering offers innovative products that apply cutting edge technology to solve problems in a unique and cost effective manner. The FUELSEP® and ALGAESEP® products add quality, value, and emissions reduction to any diesel powered boat, vehicle or industial and power generation industries. Since 1989, the Walker AIRSEP® has been one of the most widely used closed crankcase systems for diesel engines in a wide range of applications that use diesel engines, such as trucks, buses, RVs, industrial engines, and power generation. New AIRSEPS® have been designed to meet the increasing popularity of natural gas-fueled enginesl. For heavy-duty applications, the high-efficiency CCE® series AIRSEP® is the product of choice.


Pleasure Crafts

A wide selection of AIRSEP® kits specially configured for almost every diesel engine made, regardless of age or horsepower rating, including naturally aspirated engines. Designed for reliability and high performance, these AIRSEP® kits will help keep your boat free of oil mist and Noxious fumes, and look great at the same time.

Commercial Vessels

Today’s heavy duty marine applications require systems that can deliver performance, reliability and long life. Ideal for Fishing, Ferry, Offshore oil rig service, or any other high hour marine application, such as main propulsion, bow thruster, genset, or auxiliary duty diesel engines. Our new CCE AIRSEP® product line will get the job done using an exclusive two stage internal filter set.


Generator Packages
Most modern Genset packages, as of yet, do not include closed crankcase systems in their base configuration, which means it is even more important to specify a Walker AIRSEP® system. For years, top engineers, contractors, and packaging houses have specified AIRSEPS® systems for both prime and standby power, to better meet ongoing OSHA and emission guidelines.

Natural Gas Engines
As an emerging technology, Natural Gas fired engines are becoming increasingly popular. Walker Engineering offers several AIRSEP® kit configurations designed to best deal with the crankcase fumes, as well as the collected blow-by effluent of these engine types.

Auxillary Engines
Specialty diesel engine configurations for such applications as pumps systems, refrigeration, irrigation, and industrial processes require heavy duty fume disposal systems. System flexibility make AIRSEP® the best choice when designing an auxillary engine package that requires reliability and unparalleled system integration.


Military AIRSEP® Kits

Specially designed AIRSEP® systems that meet the intense demands of the U.S. Coast Guard, U.S. Navy, Navy Seals, U.S. Air Force, as well as U.S. allied forces, have been packaged with countless diesel engine applications. Walker will assist in configuring or designing an AIRSEP® system that meets certain physical, filtering, intake sound reducing, or other specialized operational criteria.
