What is one primary function of an air compressor in industrial maintenance?

One primary function of an air compressor in industrial maintenance is to power pneumatic tools. Air compressors provide a source of compressed air that is essential for operating a wide range of tools like drills, wrenches, and nailers, which rely on pneumatic energy to function effectively. This use of compressed air allows for high torque and speed output with a relatively lightweight and compact tool design, making it ideal for various maintenance tasks in an industrial setting.

While hydraulic systems also play a crucial role in industrial applications, they rely on liquid fluid pressurization rather than compressed air. Similarly, cooling down machinery and elevating liquid temperatures are functions that are typically not associated with air compressors, as these tasks are handled by cooling systems or heating elements, respectively. Thus, the ability of air compressors to efficiently power pneumatic tools stands out as their primary function in industrial maintenance contexts.
