The Vortex Combi Stand is made up of a 5 ton vehicle stand of 4" X 6" X 1/4" tubing, which can tilt the car to each side to maximize fluid recovery. It also includes the Vortex Fuel recovery tool which punches a hole in the bottom of the tank using a Beryllium punch and vacuums out the fuel; it can be assessed for quality before being sent to the correct storage tank. The system also incorporates two oil drainer arms to drain engine and transmission oil simultaneously, with raising funnels and 2" pipes coupled with a washable filter system so these arms never block up. Each funnel is controlled individually with a manually operated ball valve. You can also drain the coolant via the coolant spike which pushes in to the bottom radiator hose and vacuums out the coolant from the cars system. Also features: Tool set mounted on oil arm, four 1" double diaphragm pumps and strainers, tank connections: 3/4" JIC male connectors. *Made in the USA.All fuel tool punch systems need a minimum of 120 psi with a recommended pressure of 145 psi (10 bar). Each of the pumps uses 8 cfm (cubic feet per minute). Thus the combi system will need 32 cfm if all pumps run simultaneously. It is recommend a 15 hp compressor that will deliver between 30 and 35 cfm at 150 psi is available. A refrigerated dryer to keep the air dry is also recommended. Pumps will pump a distance of a minimum of 150ft.** Beryllium is carcinogenic and should NEVER be sharpened on a grind stone or without proper equipment. In a solid state it is safe. **
