A plant manager’s mission: Making compressed air more efficient
A plant manager had been running the same manufacturing facility for nearly a decade, but compressed air had always remained a bit of a mystery. It was essential to the operation, yet notoriously expensive. He knew the compressors were energy hogs, and he was tired of watching electricity costs climb year after year. Determined to […]
How do compressor cycle times impact efficiency?
By Ron Marshall Robert, the plant manager, was puzzled. His compressed air system had been running smoothly, but his energy bills seemed high. After reviewing his equipment, he realized the issue was the compressor’s cycle time. In a typical compressed air system, a lubricated screw compressor operates in load/unload mode. The cycle time refers to […]
How a plant manager solved his overheating problem
Chuck, a seasoned plant manager, was used to solving problems. But this summer, his compressed air system was giving him a run for his money. Temperatures in the compressor room were soaring. Alarms were sounding. One of the rotary screw compressors had already shut down twice due to high temperature. Production was stalling, tools were […]
Unlocking efficiency with compressed air system analysis
Compressed air is one of the most expensive utilities in an industrial facility — yet many operators don’t fully understand its cost or efficiency potential. That’s where a compressed air system analysis can make a powerful difference. Whether conducted by a utility, manufacturer, or independent consultant, a well-executed analysis can uncover hidden inefficiencies and chart […]
Why do your compressors keep running — even after you’ve fixed the demand side?
By Ron Marshall You’ve sealed leaks, upgraded nozzles, optimized piping, and trained your team on compressed air efficiency — yet all your compressors are still running. Sound familiar? You’re not alone. Many facilities invest heavily in improving the demand side of their compressed air system, only to see little or no reduction in compressor usage. […]
Why your compressed air system may be costing more than you think
By Ron Marshall If you’ve ever heard that it takes between 7 and 8 hp of input energy to get just 1 hp of work from a compressed air system, you might already suspect that these systems aren’t the most efficient. But the reality is even worse. In real-world industrial settings, compressed air systems often […]
Simple design changes can reduce packaging machine air consumption
Total savings over the lifecycle of the packaging machine can surpass 30%, outweighing the incremental cost of enabling components. By Steve Bain, Industry Segment Manager, Food and Packaging, Festo Original equipment manufacturers reduce packaging machine air consumption by more than 30% while increasing the speed of their packaging machines by designing those machines with valve terminals […]

Compressed air fail: Summer compressor problems
At a large machine shop in the Midwest, everything ran smoothly most of the year. The plant used a big, air-cooled screw compressor and a refrigerated air dryer to power tools, paint booths, and machines. During the cooler months, the system performed great. There were no complaints, and the maintenance crew didn’t pay much attention […]
