Here's a smart air system package. Its simple, complete, powerful, and easy to use. Steve designed this system for the RVer with large, high pressure tires. The Speed Bag allows you to store the complete kit in the RV "basement" well protected from BBQs and lawn chairs. When its time to use it just pull it out, unzip the top, and plug in the hose. All parts store neatly into the bag and its two large external pockets. If you want a nice Power Tank system that gets toted around from car to car or fits into an RV this is it. This system comes with the SuperFlow RV Series 160 PSI pre-set regulator. We do offer the HPX 200 PSI adjustable regulator for an additional cost (recommended for air tool use).
