Walker Engineering introduces new field service kits for 12″ diameter CCE AIRSEPS reg; or for AIRSEPS factory installed on Caterpillar reg; C30 and Caterpillar reg; C32 marine engines. This kit will restore your CCE AIRSEP to “like new” performance, and is ideal for seasonal service schedules.

One (1) internal coalescer filter sets and the first stage filters for either C30 or C32 systems, and replacement o-ring sets.

This Field Service Kit is also recommended for any 12″ AIRSEP used in marine applications including but not CAT C27, CAT 3508, and Mitsubishi Marine engines.

The newer CCE AIRSEPS have high efficiency disposable elements used INSIDE the AIRSEP that capture the fine oil mist found in engine crankcase emissions, so they must be periodically replaced. (They cannot be cleaned). Common primary element reference numbers; 402030, 40-2030, 40-1022, 401022

Not sure if you have the CCE type AIRSEP? -To see if your AIRSEP is the CCE system, just check to see it does NOT use springs to attach the air filter, if not, then it is a CCE AIRSEP with a V-band attachment clamp, and it has the disposable elements inside.

Direct replacement for:

  • Caterpillar AIRSEP coalescer part# 207-7469, 2077469, 270-7257, 2707257.
