Devices of this type provide pressurized gas, typically air, for a wide variety of applications. These tools function by compressing atmospheric air and storing it in a tank until needed. For example, these systems can power pneumatic tools, inflate tires, and operate spray guns.
The significance of these pressure-generating units lies in their ability to provide a portable and often more efficient power source compared to alternatives. Historically, compressed air has been used in industrial settings for heavy machinery. Contemporary use extends to smaller, mobile units that are essential in construction, automotive repair, and even home improvement projects.
