Preset regulators are notorious for problems. Why? They are never designed for a high flow rate. Remember, just because two regulators give the same output pressure does NOT mean they both have the same flow rate. Our SuperFlow regulators are designed specifically for high flow rates of CO2 and are backed by a limited lifetime warranty. I designed this system for fast easy tire inflations. Whether you have high pressure RV tires, high volume 4x4 tires, motorcycle tires or all of the above this system will do the job. If you have a CO2 tank here's the rest of the parts you'll need to make a powerful, affordable Power Tank. 180 PSI outlet pressure. This pressure is NOT recommended for air tool use or air lockers. Limited lifetime Warranty.
