Compressed Air Systems

Schhhh...! Do you hear something?


Gas Laws, Air, Compression, Compressor, Leaks


This lecture is intended to provide the fundamentals behind another system that falls under “utilities” and that is often forgotten or neglected. After a brief definition, the Ideal Gas Law and its related pressure-volume diagrams are thoroughly explained. After a review of the principles that govern compression and a description of the operations of several types of compressors, this lecture ends with an overview of a typical compressor plant with emphasis on the importance of drying compressed air and how minute leaks in the air system can become very costly.

Learning Objectives

  • Name the variables involved in the Ideal Gas Law
  • Explain and describe the relationship between those variables when considering a pressure-volume diagram

  • Describe the similarities and differences between a single-stage and double-acting compressors
  • Explain the operation of a multi-stage compressor
  • Describe the operational flow in an air compressor plant
  • Consider the importance of maintaining a leak-free system
