   13 lip 2018 · The air delivery of a compressor (known also as the free air delivery or FAD) is the expanded volume of air it forces into the air main (network) over a given period of time. The correct method of measuring this volume is given in the following standards: ISO 1217, annex C and DIN 1945, Part 1, Appendix F. ...

   Free air conditions are generally used as the reference conditions for the specification of blowers and compressors. Air is compressible with respect to both pressure and temperature and so basic thermodynamic equations and relationships are presented to show how air flow rates and conveying air velocities are influenced by these parameters.
