Compressed air pipe sizing balances air demand (flow) against the pressure drop along the pipe run. Undersized pipe wastes energy and starves your tools; oversized pipe wastes money. This calculator uses the SecureAir engineering chart (closed-loop system at 8 Bar, 5% allowable pressure drop) to recommend the right aluminium pipe diameter for your network.
Please enter a valid air demand and pipe length.
How to Use This Calculator
Enter air demand
Use your compressor's free air delivery (FAD) in CFM or m³/h — found on the compressor nameplate.
Enter pipe length
The total length of the main ring/run from compressor room to the furthest point of use.
Get the diameter
We return the recommended SecureAir aluminium pipe diameter and item codes (2.9 m & 5.8 m lengths).
