The seamless aluminum air tanks have revolutionized welded air tank construction. They have adapted a new style of technology to create a non-welded tank. The metal spinning process has allowed us to manufacture the tanks from a single piece of extruded aluminum tube. The technique of closing both ends of the tube using the base material creates a true seamless tank. The Flow Forming Technology used on our port holes reforms the base metal inward into the tank giving a superior surface area for threading. The standard mounting hardware gives the consumer a limitless range of mounting positions and angles to accommodate most mounting situations. We are proud to offer a great product that is manufacture in Fresno, California, USA.
