Air-powered tools, also known as pneumatic tools, use compressed air to operate. They are commonly used in various industries, including construction and automotive, due to their efficiency and power. These tools can include items like air wrenches, nail guns, and spray guns, which help speed up tasks that would be labor-intensive if done manually. One of the main advantages of air-powered tools is their lightweight design, making them easier to handle. Additionally, they often require less maintenance compared to electric tools. However, they do need a source of compressed air, typically provided by a compressor, to function effectively.
