Compressed Air

Compressed air can provide a safe and reliable source of pneumatic pressure for a wide range of key industrial processes. However, in many industrial plants, air compressors can account for the majority of electricity consumption. Energy savings from system improvements can range from 20 to 50 percent or more of a plant’s electricity consumption. A properly managed compressed air system can not only save energy, but also reduce maintenance needs, improve production uptime, and lead to more reliable product quality.

Top Five Energy Efficiency Measures for Compressed Air Systems

  1. Eliminate inappropriate uses of compressed air
  2. Stabilize system pressure
  3. Explore lowering pressure requirements of end uses
  4. Minimize compressed air leaks
  5. Provide compressed air of appropriate pressure and quality for manufacturing processes

J.R. Simplot’s showcase project is a new, 420,000 square foot, state-of-the-art potato processing plant that integrates innovative energy-efficient technologies, including several compressed air features, to achieve dramatic energy efficiency improvements of up to 25% while producing hundreds of millions of pounds of frozen potato products per year.

Saint-Gobain Corporation: Milford Compressed Air System Improvement

As part of its commitment to reducing its energy intensity, Saint-Gobain Corporation undertook a large compressed air system retrofit project at its Milford, Massachusetts, glass plant. After completion, the system improvement is estimated to deliver compressed air-energy savings of 15%.


The compressed air sourcebook was developed for the U.S. Department of Energy’s (DOE) Advanced Manufacturing Office (AMO). AMO undertook this project as a series of sourcebook publications. Other topics in this series include: process heating, steam, fan systems, pumping, and motor and drive systems.

Improving Compressed Air System Performance: A Sourcebook for Industry (Third Edition)

This sourcebook is designed to provide compressed air system users with a reference that outlines opportunities for system performance improvements. It is not intended to be a comprehensive technical text on improving compressed air systems, but rather a document that makes compressed air system users aware of the performance improvement potential, details some of the significant opportunities, and directs users to additional sources of assistance.


Access free software tools to help assess your compressed air system.


AIRMaster+ is a free online software tool that helps users analyze energy use and savings opportunities in industrial compressed air systems. Use AIRMaster+ to baseline existing and model future system operations improvements, and evaluate energy and dollar savings from many energy efficiency measures.

AIRMaster+ LogTool

The AIRMaster+ LogTool is a companion tool to AIRMaster+ that helps industrial users determine the operating dynamics of a compressed system. Use the LogTool first to gather critical data in preparation for AIRMaster+. Then, input that data into AIRMaster+ to model existing and future compressed air system upgrades.
