Mityvac 7300 PneumatiVac Air Operated Fluid Evacuator. The PneumatiVac, a large 8.8 Liter (2.3 gallon) capacity air operated fluid evacuator, can be used to extract a wide-range of fluid types including: Engine oil from crankcases. Brake fluid from master cylinders and most hydraulic brake systems. Gear oil from transmission cases. Coolant from cooling systems. Power steering fluid from pump reservoirs. And so much more. This shop air operated evacuator provides a clean, fast and simple way to evacuate fluids. The base mounted Venturi adds stability during operation and the air and fluid-line shut off valves prevent the unit from overfilling during use. The reservoir is constructed of durable polyethylene and will not rust or corrode. This kit comes with 5 ft. of flexible hose, two rigid dipstick tubes and a universal brake-bleeding adapter. The PneumatiVac can also be used away from the air source by first creating a vacuum, closing off both shut off valves, then transporting the unit to the job. Connect the tubing; release the shut off valves, and the PneumatiVac will do the job!
