It features a patented quiet tuned exhaust, making it one of the quieter options available, operating at 86-89 dBA. The ergonomic handle provides a secure and comfortable grip, reducing operator fatigue. It is a popular choice for professionals and DIY enthusiasts, with an affordable price tag and a 2-year warranty.

Quiet tuned exhaust

The AIRCAT 1150 Impact Wrench is a powerful and compact tool that delivers impressive torque and gets the job done quickly. It features a patented quiet tuned exhaust that ensures operation at a low decibel level of 86-89 dBA, making it one of the quieter options available for an impact wrench.

A quiet tuned exhaust, as the name suggests, is designed to reduce the noise produced by the tool it is attached to, in this case, the AIRCAT 1150 Impact Wrench. The geometry of the exhaust system can be optimised or "tuned" to maximise the power output of the engine and reduce noise.

The quiet tuned exhaust on the AIRCAT 1150 Impact Wrench is a great feature for professionals and DIY enthusiasts as it allows them to work without producing excessive noise. This can be especially important when working in residential areas or when trying to be a good neighbour.

The challenge with building a quiet exhaust is often the price. Quieter exhausts tend to be more expensive because they require additional components such as silencers, extra pipe work, and labour, which can drive up the cost. However, the benefit of a quiet exhaust is that it can help reduce noise complaints and create a more pleasant working environment.

In addition to being quiet, the AIRCAT 1150 Impact Wrench's exhaust is also designed to optimise power output. The exhaust system is tuned to ensure that reflected pressure waves arrive at the exhaust port at a particular time in the combustion cycle, maximising power. This tuning also helps to reduce back-pressure and optimise gas velocity, further enhancing the tool's performance.

Overall, the quiet tuned exhaust on the AIRCAT 1150 Impact Wrench is a great feature that allows users to work efficiently while minimising noise pollution. It is a testament to AIRCAT's commitment to providing powerful tools with reduced noise levels and ergonomic designs.

Ergonomic handle

The AIRCAT 1150 Impact Wrench features a patented, ergonomically designed handle that ensures a safe, secure, and comfortable grip for the user. This design reduces operator fatigue during extended use, making it an ideal tool for automotive repairs, maintenance, and assembly tasks.

The ergonomic handle is designed to relieve tool operator stress and is lightweight and easy to handle and operate. The lightweight composite case weighs 4.5 lbs or 2.04 kg, contributing to the overall ease of use of the tool.

The AIRCAT 1150 Impact Wrench is highly regarded by its users, with reviews highlighting its power, quietness, and build quality. The ergonomic handle is specifically mentioned as a positive feature, with one user stating that it fits in the hand well and is not very heavy.

The impact wrench is also competitively priced for its power and performance, making it a popular choice for professionals and DIY enthusiasts alike.

Twin-hammer impact mechanism

The AirCat 1150 Impact Wrench features a twin-hammer impact mechanism, which, along with its air motor, allows it to deliver high-torque output with minimal exertion from the user. The twin-hammer mechanism is designed so that the hammer can spin freely, impact the anvil, and then release and spin freely again. This mechanism allows the user to feel very little torque, even though a high peak torque is delivered to the socket.

The AirCat 1150's twin-hammer mechanism is an improvement on the "swinging weight" mechanism, which was one of the first to deliver rotary force in a series of impact blows. The twin-hammer mechanism is less susceptible to premature failure and provides enhanced durability and service life. It also requires less air consumption to achieve the same amount of torque as other impact wrenches.

The twin-hammer mechanism in the AirCat 1150 consists of a pair of hollow hammer members that are pivotally positioned relative to the hollow cage or carrier member. This allows the hammer members to rotate with the hollow cage or carrier member under drive from the air motor output shaft. The anvil is positioned inside the hollow hammer members and rotates relative to them.

The twin-hammer mechanism in the AirCat 1150 is a significant improvement in impact tool technology, providing increased durability, efficiency, and torque output.

Lightweight

The AIRCAT 1150 Killer Torque Impact Wrench is a lightweight yet powerful tool. Weighing between 4.5 and 4.63 pounds, it is easy to handle and operate, and its ergonomic handle design ensures a safe, secure, and comfortable grip, reducing operator fatigue during extended use. Its compact and low-weight design make it a great tool for automotive repairs and maintenance.

The impact wrench delivers 1,400 blows per minute, with a maximum nut-busting reverse torque of 1,295 ft-lbs and a forward tightening torque of 900 ft-lbs. This is impressive for an impact gun in its price range. The continuous air consumption rating is 8 SCFM at 90-120 PSI working pressure, with average air consumption dropping to around 4.3 SCFM.

AIRCAT claims that this tool is quieter than similar competitive impact wrenches, utilising a patented tuned exhaust muffler technology to reduce the noise level to 86 dB without sacrificing power.

Overall, the AIRCAT 1150 is an excellent value for a 1/2" air impact gun, offering a great balance of price, power, and quality. Its lightweight and compact design, combined with its impressive performance, make it a popular choice for both professionals and DIY enthusiasts.

High torque

The AIRCAT 1150 Killer Torque Impact Wrench is a powerful tool with a maximum loosening torque of 1295 ft-lb and a tightening torque of 900 ft-lb. This high torque output is impressive for an impact wrench in this price range, and it is more than sufficient for practically any job. The wrench features a twin-hammer design that delivers 1400 blows per minute for maximum hard-hitting power.

The AIRCAT 1150's continuous air consumption rating is 8 SCFM at 90-120 PSI working pressure, with the average air consumption dropping to around 4.3 SCFM. This means that a commercial shop with a large air compressor will have no trouble powering the wrench to its full capacity. However, for home or farm users, a sufficient compressor is required to achieve maximum power. AIRCAT recommends a direct connection to a 3/8" or larger diameter air hose, 25 feet or shorter in length, for optimal performance.

The AIRCAT 1150 stands out for its high torque capabilities, delivering exceptional performance for automotive repairs, maintenance, and assembly tasks. Its innovative design includes a patented quiet tuned exhaust, ensuring operation at a noise level of 86-89 dBA, making it one of the quieter options available. The durable composite housing and ergonomically designed handle provide both strength and comfort, reducing operator fatigue during extended use.

The AIRCAT 1150 Killer Torque Impact Wrench is an excellent choice for professionals and DIY enthusiasts seeking a high-torque, durable, and comfortable impact wrench. With its impressive torque output, efficient air consumption, and quiet operation, it offers a great balance of performance, ease of use, and value.
