How do our units keep their High Speed and Torque under load?
The patented 'O' ring controlled governor in the turbine delivers more power on demand by increasing the flow of air as the turbine comes under load to keep the speed high under load.

The 'O' ring delivers efficient power on demand staying within 20% of rated speed up to 80% of maximum rated power. The 'O' ring also regulates airflow on demand, reducing air consumption.

Air Turbine Technology, Inc. has developed and patented higher power turbines to maintain higher cutting speeds with our double turbine design. Combined twin turbines produce up to 1.4 HP / 1.04 kW to enable Air Turbine Tools® to mill tool steel, kevlar, and to maintain high peripheral cutting speed in corners and pockets.
These air turbine spindle, air turbine tools, air turbine motors are all products of air turbine technology, inc. Designed to out perform the cnc spindle or cnc machine spindle with a revolutionary pneumatic motor, air turbine spindles are designed to work with chiron, dmg moro seiki, doosan, fadal, emco, haas, hardinge, hartford, hermle, hurco, hwacheon, kitagawa, makino, mazak, okuma, romi and many other cnc machines. Also compatible with brother, fanuc, haas, matrix and other drill-tap machines for cnc milling with our high speed precision pneumatic air spindles. Our air turbine motors are high speed, efficient, pneumatic motors. These pneumatic motors are designed for lathe, robot, machining, debarring, finishing, routing, drilling and milling, a very versatile fixture mount. We also manufacture air turbine hand tools that are engraving tools, finishing tools, grinders, pencil tools, routing tools and marking tools. Air Turbine manufactures hand tools, grinders, pencil tools, debarring tools, finishing tools, which are all low vibration tools, precision tools, and ergonomic tools. These tools are performance tools, low weight tools, with an air turbine motor. Air Turbine motors require no oil, have no gears or vanes, for reliability. Made in USA.
