Maintaining Compressed Air Filters and the Purpose of Differential Pressure Monitoring Devices

By Mark White, Parker Hannifin

The foundation of any purification system is its filtration and of the ten main contaminants found in a compressed air system, filtration is responsible for the treatment of nine of them. Coalescing filters are the most important piece of purification equipment as they reduce six of the ten contaminants and a look in any air compressor room will find a pair of coalescing filters (backed up with dry particulate and oil vapor removal filters).

ISO 50001: How Manufacturers Can Achieve a Low-cost and Low-carbon Future

By Graham Coats, Energair

For an organization to prove that it meets the standard it has to undergo a management system audit, either internal or external. The question, therefore, is how can those utilizing compressed air effectively evaluate their assets’ performance as part of an ISO 50001 energy management system and, in doing so, grow their bottom line and minimize their negative environmental footprint.

Unilever Ice Cream Plant Reduces Compressed Air Consumption with Pneumatic Energy Efficiency Module

By Randy DeForge, Festo

Electricity and compressed air play an important role in the thermal and kinetic processes for everything from mixing and extruding the ingredients, deep-freezing to -13°F (-25°C), dipping into various chocolate coatings through to final packaging. Energy efficiency is therefore right at the top of Unilever’s list of priorities. As part of the Unilever Sustainable Living Plan, this global corporation has succeeded in saving more than \$186 million in energy costs from efficiency improvements in production alone since 2008.

The Pros and Cons of Single-stage and Two-stage Rotary Screw Air Compressors

By FS-Curtis

Among the many “systems” plant personnel are concerned with, the compressed air system often provides the biggest opportunity for improvement and overall savings. There are many manufacturers and several air compressor technologies to choose from. Reciprocating or rotary? Fixed speed or variable speed? Oil flooded or oil free? Single-stage or two-stage technology? It’s enough to make anyone want to run and hide!

Dutch Glass Container Plant Compressed Air System Makeover Increases Uptime and Energy Savings

By Mike Grennier, Compressed Air Best Practices® Magazine

To improve the delivery of compressed air at the plant, which is supplied by low-pressure and high-pressure compressed air systems, the manufacturer took an important first step by using airflow meters to monitor and measure the performance of both systems. Subsequent planning based on actionable data led to a unique compressed air system upgrade that increases the plant’s ability to maintain peak production of high quality glass bottles and containers at all times – while saving \$150,000 per year in energy costs. The project also delivered a payback of less than two years.

Is Your Controller a Blast From the Past?

By the Compressed Air & Gas Institute

Advances in phone technology dramatically improve their function and our experience. More storage, faster speeds, enhanced communication options, bigger and brighter display….and so on. As a result, today’s phones are significantly more powerful – improving our productivity and changing our lives. As for the technology laggards, obsolescence eventually prompts change. Repairing or replacing parts and accessories on the old phones is an increasing challenge. Eventually they have to succumb to technology.

How to Detect and Eliminate Varnish in Oil-Injected Rotary-Screw Air Compressors

By Michael Caruso, AMSOIL INC.

Varnish is a leading cause of airend failure in oil-flooded/injected rotary-screw air compressors. The purpose of this article is not to cover every scenario conducive to varnish formation, but to point out that many factors need to be considered when it occurs, and methods are available for its detection. Ultimately, it’s up to both the oil manufacturer and maintenance professional to ensure the oil used is up to the task of resisting varnish and maximizing air compressor performance and life.

Compressed Air Guidelines for Varying Production Levels

By Paul Humphreys, Atlas Copco Compressors LLC.

Companies will experience periods of increased production, as well as periods of slower or stopped production. It’s the nature of being in business. Understanding the implications of these business shifts for compressed-air installations (the powerhouse behind a facility’s production) is key for ensuring that air compressors remain functional and efficient. Here are guidelines to ensure your facility’s compressed-air system operates at top performance, no matter the speed of production.

How Centrifugal Air Compressor Specifications Impact Costs

By the Compressed Air & Gas Institute

In an ever-evolving world of regulations, requirements, and legal ramifications, it can be all too easy to want to cover all the bases by adding a wide range of industry codes and standards to any project being put out for bid. Many assume that if the purchased equipment meets all the requirements of every developed code and standard then surely it will be a reliable and safe machine to operate with the best performance and energy efficiency. However, many of these codes and standards are developed with a tremendously broad range of machinery and equipment in mind and they may not always fit well with the specific project being developed. Compliance to these codes and standards may require very costly modifications to a manufacturer’s standard product for little to no real benefit.
