Compressed air calculator

Calculator

Compressor sizing

Enter your known air consumption and required operating pressure. Get an initial estimate to help us develop a suitable compressed air solution.

Air consumption input method Total air consumption · l/min Air consumption expressed as free air delivery (FAD). Required pressure at the point of use · barg The operating pressure required by the equipment or tool.

Adjust usage and capacity margin

Simultaneous use · % 100% means that all entered units operate simultaneously. If your total consumption already accounts for simultaneous use, leave this at 100%. Capacity margin · % 15% is an adjustable example assumption.

This is a simplified example calculation. Actual requirements may differ. Have the solution checked by a qualified specialist before purchasing or installing equipment.

Compressed air pipe pressure drop estimate

An informative tool for an initial assessment of pipework. The result is not an approved engineering design.

Input data

Pressure at the pipe section inlet · barg Deduct any pressure losses upstream of this section from the compressor pressure setting. Flow rate · l/min (FAD) Enter the free air flow rate through this pipe section in litres per minute. Actual pipe length · m Allowable pressure drop · bar Internal diameter to check · mm Use the actual internal diameter specified by the manufacturer.

Calculation assumptions

This is a simplified example calculation providing an initial estimate. Developing a more detailed solution requires an assessment of the overall compressed air demand, equipment usage, pipework layout and pressure losses across the system components.

Use of results and responsibility

These calculators provide informative example calculations based on simplified assumptions and user-supplied data. Results may differ significantly from actual conditions and do not confirm the suitability or safety of equipment or pipework.

Users are responsible for the accuracy of their input data, independently verifying the results and any decisions based on them. Results must not be used as the sole basis for selecting, purchasing or installing pipework or equipment. Have the solution checked by a qualified specialist before implementation.
