A portable, air-powered version of ESOC's sealed oil change system was introduced at the annual meeting of ATA's Technology and Maintenance Council. The 850 Portable can be rolled on its wheels through a terminal lot or carried in a service truck, and is particularly well suited to servicing refrigeration unit engines, according to ESOC.
The system purges the engine and its filters of old oil, replenishes filters and crankcase automatically, and pre-lubes the engine for initial startup.
