The tables below provide the values for the flow rate in standard cubic metres of Nitrogen at the
indicated operating conditions. The flow rates of other gas types may be estimated using the
conversion factors from the table on the right.
For more specific flow rate flow rate calculations please refer to our data sheet “Performance diagram”.
The tables show the flow rates with only one side delivering the gas!
