Air Starter Motors
Vane air starters are the most commonly used air starters throughout the world. The vane motor develops maximum horsepower at a much lower speed of 5,000 to 6,000 rpm, and only requires a small amount of lubrication for maximum life. The decreased speed of the vane motor improves bearing life, and delivers more torque per pound of weight than piston air motors.
