Mobile waste oil drains are used for gravity or suction collection of motor oil and gear oil, as well as other automotive, non-aggressive A-III class fluids. Models for gravity collection are fitted with a telescopic bowl and they can be used under vehicle lifts or inside lubrication pits for collection of the used fluid. All drains include a 5 gallon capacity, height adjustable collection bowl for wider reach. All 27 gallon models include over-sized extension bowl with anti-splash screen. All models are equipped with a level gauge. Once full, depending on the model, the reservoir can be discharged either using a remote pump through a hydraulic type connector fitted to the bottom of the unit or pressurizing the unit reservoir at 3.5 psi maximum.
