Airetrol Air Driven Motors


Airetool motors control expansion by accurate measurement of torque. They automatically stop

expansion accurately according to predetermined setting.This prevents over- and under- expansion of

tubes, assuring uniformly tight tube joints, providing maximum holding strength for individual tubes. Strong,

lightweight aluminum housings provide easier handling and less fatigue. Rugged drive combines precision

control which measures torque output. All AIRETROLs include torque sensing cams designed and

manufactured specifically for tube expanding applications.
