This beast is the most powerful 1/2 inch air impact wrench in its class. With a hard hitting twin hammer setup it delivers 1295 ft-lb loosening torque and 900 ft lb max torque.
- 1/2 inch square drive
- Air consumption 8 Cfm
- Free speed RPM, 9000
- IPM = 1400
- Quiet exhaust (86 dBA)
The AIRCAT 1150 ships with a swivel air inlet and offers hard-hitting twin a hammer technology. The comfortable, ergonomically-designed handle is easy to hold for extended periods and is reasonably lightweight, with a readily accessible and easy to operate forward and reverse switch. Despite its light weight, the 1150 is actually quite durable with its composite-constructed housing. And with a quiet exhaust system – it’s more user-friendly then some of the bigger, louder air impact wrenches.
Both the power and performance of this impact wrench is impressive – delivering a considerable 1295 foot-pounds of torque for loosening and a maximum forward motion torque of 900 foot-pounds. That’s a whole lot of power – certainly enough for most any job.
What you’re getting is impressive power and torque in an impact wrench that also operates at a significantly reduced noise level. According to AIRCAT, this gun offers the strongest and hardest-hitting hammer construction in the market. Its rotor is 15% bigger than competing brands.

As one auto technician noted, the AIRCAT seemed less noisy and much easier to use when working side-by-side in a shop with others doing similar work but with different equipment. If you’re used to those tool truck impact wrenches – you might be tempted to overlook the AIRCAT thinking it lacks power. But that would be a mistake. Use This AIRCAT once and you’ll see.

AirCat – Built Tough!
This thing is built tough. Numerous reports abound of techs accidentally dropping their Nitrocat air guns from significant heights or off tool carts and having them crash to the concrete floor, or land in a pool of hydraulic oil. Yet these air tools sustained only minor scratches and fired up without a problem – just like they did before.
If you’re only planning to use your air wrench occasionally, then the air compressor you’re using is not that important and you can get by with a small tank air compressor. The trick is to let the tank fill fully so you have maximum airflow through to the wrench
