The EVACUMaster Centrailzed Used Oil Evacuation System from Samson is a completely closed loop system, known as ECOES, that evacuates the engine oil from the vehicle directly into an above-ground used oil storage container equipped with an environmental overflow protection system. The system evacuates oil in the pan below drain plug level, with 2.5 qt. drain pans evacuating in 90 seconds and 5.5 qt. drain pans evacuating in 180 seconds.
