What is the Pneumatic Impact Wrench?

These are compressed air powered impact wrenches. Pneumatic or air impact wrenches are widely used in automobile repair shops, automotive assembly lines, heavy equipment manufacturing etc. They have some distinct advantages when compared to electric wrenches.

A pneumatic impact wrench is simple in engineering design and hence they are relatively inexpensive. Since there are no electronic or electric parts, the chances of a malfunction are very rare. But the biggest advantage is that unlike its counterpart the pneumatic impact wrench won’t get heated. Any heat generated by the rotating elements inside the impact gun is cooled by the circulating compressed air. This makes the pneumatic impact wrench ideal for assembly lines since it can be used for long working hours continuously without worrying about overheating.

The overheat protection by the air flow and relatively simpler design makes pneumatic impact wrenches more durable. Additionally, they are easy to repair and maintain.

In addition to the standard ½ inch square shank, pneumatic impact wrenches also come with 3/8 inch, ¾ inch, and 1-inch shanks. Pneumatic Impact Wrench.
