Compressed air
Location

90% of industrial facilities use compressed air in their process. Unfortunately, most compressed air systems are inherently inefficient, converting less that 20% of their energy input into useable compressed air. Consequently, reducing unnecessary compressed air usage and improving the efficiency of the compressed air systems themselves are excellent energy-saving strategies.
Compressed air is often used because it is believed to be convenient, safe, and labor-saving. These advantages may justify the high cost of compressed air, but often more energy-efficient alternatives exist.
Air leaks, improper pressure regulation, and airflow restrictions can easily reduce a system's useful capacity by 50 percent or more. Typically, these problems are "solved" by adding a new compressor, when fixing the problem would be much more cost-effective and energy-efficient.
