What is the role of an air compressor in a compressed air system?

The role of an air compressor in a compressed air system is to compress air to a desired pressure level. This is essential for the functionality of various pneumatic tools and equipment, ensuring that they receive air at a sufficient pressure to operate effectively. Air compressors take in atmospheric air and reduce its volume, which simultaneously increases the pressure of the air to the levels necessary for use in different applications, such as powering tools or aiding in medical gas delivery systems.

While storing compressed air (the first choice) is a function of air storage tanks, it is not the primary role of the compressor itself. Filtering contaminants (the second choice) can be accomplished by separate filtration systems and is typically not a function of the compressor. Monitoring pressures (the fourth choice) is handled by pressure gauges and other instruments, rather than the compressor in itself. The compressor's main function remains focused on the act of compression to achieve the required pressure for practical usage in the system.
