John Dow Used Oil Storage System - 180 Gallon - AGS-180D

The pump is a 1" air-operated diaphragm pump, so it requires a compressed air supply from your facility. The system includes an air supply connection hose with quick-coupler, a manual air inlet shut-off valve, and an air filter/regulator to make the connection to your existing compressed air source straightforward.

The double-wall tank provides 110% secondary containment, meaning the cavity between the inner and outer walls can hold more than the entire 180-gallon capacity. If the primary inner wall ever leaks, the outer wall captures and retains the full volume, preventing environmental contamination on the floor or ground.

An automatic air shut-off is built into the system and cuts off the air-operated pump once the tank reaches capacity. This eliminates the need for continuous manual monitoring during transfer operations and reduces the risk of spills caused by overfilling.

The air-operated diaphragm pump has a 30 GPM capacity, so a full 180-gallon tank can be filled in approximately 6 minutes under optimal conditions. A 3/4" x 10" suction hose with a quick-connect coupler is included for drawing oil from vehicles or drain pans, and a 2" drop tube with a camlock fitting and dust cover is provided for the tank inlet.

Yes, the same UL-listed double-wall tank design is offered in capacities ranging from 180 to 500 gallons, so facilities that generate more used oil can choose a larger model that fits their storage needs.

The locking security/environmental cover serves a dual purpose: it restricts unauthorized access to the tank contents and helps protect the interior from environmental contaminants such as rainwater, debris, or airborne particulates that could degrade oil quality or create disposal complications.
