Ingersoll Rand vane air starters are the most commonly used air starters throughout the world. Their simple, rugged designs are easy to maintain and their durability legendary. 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.
