Waste Oil Drain, Pressurized, 21 Gallon, without Safety Interlock (Liquidynamics - Model 24176)

The used fluid simply gravity drains into the large 29” diameter, 3½ gallon drain pan, which then drains into the 21 gallon holding tank. Approximately 7 to 10 PSI of shop air is used to quickly and easily evacuate the fluid from the tank, a safety relief valve prevents over-pressurization. Alternatively, a dry break disconnect kit is available if evacuation via a double diaphragm pump is preferred.
