With this pneumatic oil extraction device, which operates using vacuum pressure, transmission or engine oil can be easily and thoroughly removed from vehicles without an oil drain. The vacuum principle reliably directs the oil being extracted into the large tank of the device, and the closed-loop principle minimizes the risk of environmental contamination from leaking fluids. The built-in safety valve prevents overpressure from building up in the closed system during extraction. The air pressure for extraction can be conveniently adjusted via a regulator, and the collection container is equipped with a level indicator to ensure timely emptying of the tank.
