Compressed Air Demand Estimator
Estimate average compressed-air demand for cyclic food processing and packaging equipment.
Estimate free-air demand for cyclic equipment
Calculate average compressed-air demand from air used per cycle, cycle rate, machine quantity, active duty and leakage allowance.
Who should use this estimator?
Factory engineers
Prepare a preliminary compressor and distribution load schedule.
Packaging-line buyers
Estimate air demand from cylinders, valves, clippers and actuators.
Maintenance teams
Understand how cycle rate, simultaneous operation and leakage affect demand.
Free-air demand = litres/cycle x cycles/min x machines x duty x allowance
What final compressed-air design must include
Pressure requirement
Verify minimum pressure at each machine after dryers, filters and distribution losses.
Peak demand
Short high-flow events may require local receivers even when average demand is modest.
Air quality
Food-contact risk determines filtration, drying, oil control and monitoring requirements.
Compressed air demand FAQ
What is free air?
Free-air delivery expresses compressor output referenced to inlet atmospheric conditions rather than compressed pipe volume.
Can average demand select the air receiver?
No. Receiver sizing also depends on peak flow, pressure band, compressor control and acceptable pressure drop.
Should leakage be included?
Yes for planning, while the factory should also maintain an active leak-detection and repair program.
