Combined waste oil suction and drain unit with a 27 gallon capacity allows the drainage of waste oil through the dipstick tube with the use of the proper suction probe. It can also be used as a gravity oil drain.

Waste oil suction is carried out by an air operated vacuum pump with no moving and no wearing parts, using a suction probe or connector inserted into the oil dipstick tube. Can be used as a portable unit, disconnected from the air supply, once the vacuum is created inside the container. Discharge is carried out through a 6-1/2 foot discharge hose, pressurizing the unit at 7 p.s.i. using a tire inflator (see page 2 for additional options). Waste oil gravity collection is carried out using a 5 gallon capacity, height adjustable, oversized collection bowl with an anti-splash screen that can hold used oil filters for draining.
