An air compressor is a device that converts power into potential energy stored in compressed air. It works by drawing in air and compressing it, which increases the air's pressure. This compressed air can then be used to power various tools and equipment, such as nail guns, paint sprayers, and air wrenches. Air compressors come in different sizes and types, including portable compressors for small jobs and larger, stationary models for industrial use. They are essential in many industries, from construction to automotive repair, making tasks easier and more efficient by providing a reliable source of compressed air.
