What is Turbine Airboost Technology? Standard leaf blowers use the tips of the fan blades on the rotor to drive air forward, which doesn't take full advantage of the length of the fan blades. By turning the rotor 90º and using the technology found in turbine jet engines on airplanes, Sun Joe's revolutionized rotor propels air forward with more force, using the elongated length of the tube for a more concentrated air blast.
