Lowering pressure by 10 psi (~0.7 bar) on 200 HP of compressors — 8,000 h/yr, $0.08/kWh
≈ $5,100/yr
~64,000 kWh — rule of thumb: ~1% per 2 psi
The approach
Optimizations — cut your compressed air costs
Propose and prioritize the worthwhile optimizations for your compressed air network.
The optimizations
- Proper compressor sequencing
- Optimizing the operating pressure bands
- Eliminating compressed-air uses
- Heat recovery
- Adding variable-speed drives (VSD)
- Equipment replacement with financial incentives
- Replacing obsolete, energy-hungry accessories (filtration, distribution)
- Eliminating over-maintenance
- Optimizing maintenance routes
- Condensate treatment
- And more, depending on your system
Savings examples
Eliminating 3,000 h of unloaded running on a 100 HP compressor — $0.08/kWh
≈ $4,800/yr
~60,000 kWh — unloaded ≈ 25% of full load
Shutting down a 75 HP compressor running 8,000 h/yr — $0.08/kWh
≈ $38,400/yr
~480,000 kWh — at full load
Indicative estimates. Assumptions: ~0.8 kW/HP at full load, unloaded ≈ 25% of full load, ~1% energy per 2 psi. Actual savings vary by system.

Estimated leaks:—(— · —)
Rule of thumb: a system typically has 10–30% leaks. E.g., a 100 HP compressor → ~40–120 SCFM (10–30 HP, 7–25 kW).
Assumption: ~0.2 kW/SCFM (≈ 4 SCFM/HP at ~100 psi). Indicative estimates; actual results vary.
