The primary purpose of an air compressor in a compressed air system is to increase air pressure. An air compressor functions by taking in ambient air, then reducing its volume, which results in a corresponding increase in pressure. This pressurized air can then be used for various applications, such as powering pneumatic tools, inflating tires, or serving as part of a process control system.

While other aspects like removing moisture or regulating airflow are important in the overall operation and maintenance of a compressed air system, they are not the fundamental purpose of the air compressor itself. The compressor's main job is to generate and maintain the necessary pressure to meet the demands of the system it serves.
