Sitting on his desk the day Brian began his new job as Plant Engineer for Carbo Ceramics’ McIntyre, GA facility was a proposal to purchase a new 150 HP air compressor as a backup machine. The facility already had six of these machines and, yes, all six ran almost continuously.
Auto
This stamping plant is a 2.5 million-square-foot facility with over two thousand employees. At the time of the assessment, the plant was processing approximately 1,600 tons of steel per day into automotive vehicle components and parts such as body parts.

Food
This article presents a case study of Grimmway Farms; a carrot growing and packing firm located in California’s Central Valley that was able to improve its compressed air system efficiency after implementing system automation and making relatively small equipment and piping changes.
Medical
In the U.S. as an example, the NFPA has taken the view that if your compressor draws in good clean ambient air, the air stays clean through the compressor, is then dried and filtered, when you deliver it to the patient it will be entirely satisfactory. After all, when you went into the hospital that’s what you were breathing and when you leave you will breathe it again!
Metals
This aluminum mill spends $369,000 annually in energy costs to operate their compressed air system. This system assessment recommends actions reducing annual energy costs by $120,000 and improving productivity and quality by delivering clean, dry compressed air.
Paper
A paper mill in Wisconsin reduced its’ yearly water consumption by 547.5 million gallons and reduced its’ yearly air compressor maintenance costs by $470,000.
Pharmaceutical
Roxane Laboratories, Inc., a subsidiary of Boehringer Ingelheim Corporation located in Columbus, Ohio, created a world-class air system that generated $61,314 per year in electrical energy cost savings (1,156,868 kWh), improved productivity and quality, and allowed the successful completion of a significant plant expansion.
Plastics
Over the last several decades, Air Power USA has reviewed many various types of plastic injection molding operations throughout the U.S.
Power
Nuclear power plants produce electricity for people, business and industry. Electricity is produced in a similar fashion as fossil fuel (i.e., coal, oil, etc.) power plants, using steam to drive a turbines which spin an electrical generator, producing the electricity.

Finding the most effective, reliable and economical method for separating and concentrating die lubricant is no easy task for die casting plants – and the situation at the Metaldyne aluminum die casting plant in Twinsburg, Ohio was no different.
A leading soft drink bottling manufacturer’s compressed air needs were threatening to exceed its Michigan plant’s compressed air capacity. Faced with the cost of buying a new compressor, the soft drink bottling manufacturer re-assessed their compressed air use to identify compressor and energy savings opportunities. In the audit, the soft drink bottling manufacturer identified the use of compressed air in a gap transfer as a source of compressed air and energy inefficiency.

The U.S. Environmental Protection Agency (EPA) recognized the first group of manufacturing sites that have met the Energy Star Challenge for Industry and reduced their energy intensity by 10 percent within 5 years or less. The U.S. manufacturing industry is responsible for nearly 30 percent of greenhouse gas emissions in the United States and spends almost $100 billion annually on energy.

Recognizing its leadership in efforts to reduce greenhouse gas emissions through energy efficiency, the U.S. Environmental Protection Agency (EPA) has honored NewYork-Presbyterian Hospital with an ENERGY STAR Partner of the Year Award for Sustained Excellence in Energy Management, the energy program's highest honor. It is the fifth time the Hospital has been honored by the EPA — the most of any hospital in the country.

Large hospitals often use compressed air for important operational related end uses. The systems that produce this air need to supply clean and dry compressed air with a high level of reliability. These systems are not immune to efficiency problems as is the case for any compressed air system.

Hazardous breathing conditions exist in routine industrial operations, such as hospitals, abrasive blasting, paint spraying, industrial cleaning, and arc welding. In these and other operations that introduce contaminants into the workplace, supplied-air respirators are frequently used for worker protection.

A good-size hospital with 200 beds and ten operating rooms can have a medical air system, a laboratory air system, and pneumatic air systems. The medical air systems must all follow the NFPA 99 guidelines. We follow these guidelines, from the beginning, when we assess the demand for air in a hospital.

The most abundant contaminant in any compressed air system is water. This can be in either liquid or vapour form. Atmospheric air is already very wet, and becomes saturated when compressed. This water vapour will condense when the temperature drops, after the compressor, and will damage air receivers, pipework and equipment. For this reason coalescing filters and then dryers are used to remove the bulk of this water.
