air compressor flow rate. (FAD or Nm3/h) 1

[hassann]

Hi ,
it might be a pretty basic question, but any help will be great. I'm trying to select an air compressor with capacity of 580 Nm3/h. I'm having a bit of difficulty finding the right decision to doing it. In manufacture catalogue data are based on FAD (free air delivery) and is 588. Is there any difference between FAD and nm3/h?
thanks,

Hi,
To avoid confusion, consider the document attached where most of your doubts should be clarified.
To mitigate the risks, consider calculating your needs in term of mass thus you can verify its constancy everywhere (inlet, outlet of the machine).
I must admit this could be source of mistake.
Good luck
