CAGI Releases Compressed Air Purity Guide

By Chad Larrabee, Technical Editor, Compressed Air and Gas Institute

The Compressed Air and Gas Institute has released a Compressed Air Purity Guide to help industries achieve clean, dry compressed air and improve system reliability. The guide applies ISO 8573-1 to classify contaminants such as particles, water and oil, and defines purity levels for plant, instrument and process air. It also outlines key technologies like dryers and filtration systems to ensure optimal air quality and equipment protection.

Using ISO 8573-1 to Test Compressed Air: Clearing the Confusion

By Ruby Ochoa, President, Trace Analytics, LLC

Compressed air is used in more than 70 percent of all manufacturing activities, ranging from highly critical applications that may impact product quality to general “shop” uses. When compressed air is used in the production of pharmaceuticals, food, beverages, medical devices, and other products, there seems to be confusion on what testing needs to be performed.

Understanding Centrifugal Air Compressor Capacity Controls

By the Compressed Air and Gas Institute

Centrifugal compressors are dynamic, and each has a characteristic curve of rising pressure as capacity decreases. Without any control system, the compressor would operate along this natural curve. A centrifugal compressor's flow and pressure are typically controlled by a combination of an inlet control device and an unloading valve (UV).

Energy Performance Indicators Support ISO 50001 and ISO 50006

By Ron Marshall for the Compressed Air Challenge®

Organizations across the world are gaining control of their energy spending by measuring and managing their utilities. In doing so, they may be using standards such as ISO 50001:2011 (energy management systems — requirements with guidance for use) to help set up an energy management system (EnMS) that will improve their energy performance. This improved performance might lower energy bills, making products more affordable in the marketplace and improving an organization’s carbon footprint.

A Compressed Air & Gas Institute Session - Heat Recovery from Industrial Compressed Air Systems

By Compressed Air Best Practices® Magazine

The rise in energy prices is an unwelcome reality in today’s manufacturing and business environment. And while the rate of price increases for natural gas, heating oil and electricity may vary from year to year, the upward trajectory is clear. Energy cost reduction strategies are vital to staying competitive. Compressed Air Best Practices® Magazine recently discussed heat recovery, from industrial compressed air systems, with the Compressed Air and Gas Institute (CAGI). Their inputs should provide you with some insight in energy-saving technology.

Evaluating Different Blower Technologies on a Wire-to-Air Basis

By Andrew Balberg, Business Development Manager–Low Pressure, Atlas Copco

In the absence of official third party specifications on energy efficiency, it is difficult to evaluate and compare blower technologies fairly and effectively. The lack of readily available evaluation tools leads to misinformation and unfair comparisons between technologies. Further, the performance verification process is difficult to prove.

CAGI Performance Verification Program for Air Compressor and Dryer Selection

By the Compressed Air & Gas Institute

Plant engineers do not purchase air compressors or compressed air dryers on a regular basis. There may be decades between purchases, and with today’s more reliable and durable compressed air equipment, the interval between purchasing decisions grows ever longer. This lack of purchasing frequency, coupled with the significant investment in productivity that compressors and dryers represent, means it is important to make the right decision.

Compressed Air Best Practices® Magazine interviewed Rick Stasyshan, Technical Consultant, of the Compressed Air & Gas Institute

Compressed air is viewed as industry’s fourth utility. Compressed air is frequently the only means of effectively, consistently, efficiently and safely powering certain machinery and processes. It enables users to perform critical work to manufacture, build and process the products we use every day. The world cannot function without compressed air. CABP recently caught up with Rick Stasyshan, the Compressed Air and Gas Institute’s recently appointed Technical Consultant, to shed some light on CAGI’s activities and industry involvement.
