Compressed Air System Efficiency
Estimate how much compressed air leaks may be costing your facility each year. Use leak size, system pressure, operating hours, and electricity cost to calculate estimated CFM loss, annual energy waste, 3-year cost, and 5-year cost.

Small air leaks can create a surprisingly large energy drain over time. Enter your facility assumptions below or use the defaults: $0.12/kWh, 4,000 operating hours per year, and 100 PSI.
Leak Size Reference Table
The larger the leak and the higher the system pressure, the more compressed air is wasted. Even a small leak can become expensive when the system runs thousands of hours per year.
| Leak Size | Approx. Diameter | Common Visual Comparison | Operational Impact |
|---|---|---|---|
| 1/64" | 0.0156 in. | Very small pinhole | Often overlooked, but costly across long operating schedules. |
| 1/32" | 0.0313 in. | Small pinhole | Can create measurable CFM loss in continuous-use systems. |
| 1/16" | 0.0625 in. | Noticeable small opening | May force compressors to cycle more frequently or run longer. |
| 1/8" | 0.125 in. | Large leak point | Can waste significant energy and reduce system capacity. |
| 1/4" | 0.250 in. | Major leak | Can materially impact pressure stability and operating cost. |
| 3/8" | 0.375 in. | Severe leak | Can represent a major compressed air demand source by itself. |
Why Compressed Air Leaks Matter
Compressed air is one of the most useful utilities in an industrial facility, but it is also one of the easiest to waste. Leaks can increase energy consumption, reduce available CFM, create pressure instability, and make compressors work harder than necessary.
Higher Energy Cost
Leaks create artificial demand. Your compressor may run longer or cycle more often just to replace air that never reaches production equipment.
Reduced System Capacity
Air lost through leaks can limit available CFM for tools, equipment, and production processes that need stable air supply.
More Wear on Equipment
When compressors run harder to maintain pressure, components can experience added heat, duty cycle stress, and maintenance demand.
