Why the term 3rd utility? Simply because almost all industry is it at automobile, semiconductor, pharmaceutical, or even dentists to run the drill, they need compressed air.Without compressed air, manufacturers or your mechanic will be changing tires with brute force and cannot work efficiently.
Most manufacturing machinery requires at least some sort of energy to power them.For general application and non heavy duty jobs, compressed air is the best choice due to cleanliness if compared to a hydraulic system.
Compressed air is generated by air compressors, many types of compressors are available in the market these days such as piston type, screw element type, scroll type, vane type, and high volume centrifugal/turbo type just to name a few.However, we will elaborate on the compressor type in the future topic.
An air compressor gets its "source" from ambient air traveling through the inlet air duct and into a compression chamber. Inside the compression chamber, overpressure will be created by reducing the air volume rapidly.
