An air compressor is a device that converts power into potential energy stored in pressurized air. It works by drawing in air and compressing it, which increases the air's pressure. This compressed air can then be used for various applications, such as powering tools, inflating tires, or providing air for industrial processes. There are different types of air compressors, including reciprocating compressors, rotary screw compressors, and centrifugal compressors. Each type has its own mechanism and is suited for specific tasks. Air compressors are commonly used in both residential and commercial settings, making them essential tools in many industries.
