The ZE6EV 6-Gallon Fluid Evacuator was built with professionals in mind and was designed to be used when changing oil, transmission fluids, and more for automobiles, light trucks, and equipment with small engines. This fluid evacuator uses the included probes to remove fluids without having to remove the drain plug on the pan on passenger vehicles which limits shop liability. Just pressurize the tank with a shop air connection, attach the appropriate probe, insert into the dipstick and watch the oil flow into the evacuator. This unit is also portable so there is no need to leave attached to an air hose during operation after pressurization. This portable and compact fluid evacuator is ideal for do-it-yourselfers wanting to perform maintenance on lawn & garden equipment, motorcycles, ATVs, and more!
