An air compressor is a machine that converts power into pressurized air, which can be used to operate various tools such as nail guns, spray painters, and impact wrenches. Air compressors are versatile, serving industries from construction to automotive, as well as home applications like inflating tires or powering airbrushes. They work by drawing in air, compressing it, and storing it in a tank for use on demand.

Air compressors vary in type and capacity, including portable and stationary models. Portable air compressors are convenient for smaller tasks, while industrial models provide higher air pressure and capacity for heavy-duty applications.
