Compressed Air Artificial Demand Calculator — Pressure Reduction Energy & Cost
Estimate avoidable compressed-air demand and energy caused by operating above the required pressure, using measured flow, pressure sensitivity, specific power and annual hours.
Inputs
Live results
- Pressure reduction 10 psi
- Avoidable flow 100 cfm
- Estimated power saving 0.18 kW
- Annual energy saving 1.08 MWh
- Annual indicated saving 108
Formula
Avoidable flow=Q×sensitivity×ΔP; kW saved=avoidable flow×specific power.
Worked example
1,000 cfm with 1%/psi sensitivity and a 10 psi reduction avoids about 100 cfm.
Assumptions and limits
- Pressure sensitivity is site-specific; measure or test it where possible.
- Verify critical end-use minimum pressure before reducing system pressure.
FAQs
What does this Compressed Air Artificial Demand Calculator calculate?
Estimate avoidable compressed-air demand and energy caused by operating above the required pressure, using measured flow, pressure sensitivity, specific power and annual hours.
Can I use this for a final design?
Use it for screening, diagnostics and opportunity sizing. Validate final design against measured plant data, OEM limits and applicable standards.
Why does the calculator show intermediate results?
Intermediate engineering quantities make bad inputs and unrealistic assumptions easier to spot before a decision is made.
