Step 5: Calculating losses from
leaks
Leaks in compressed air systems are one of the greatest
problems and result in enormous costs if there is no
systematic control.
A small plant with only a few connections into the
system should aim for a leakage rate of less than 5% of
demand, but a large manufacturing site cannot expect to
have a leakage rate better than 15-20% of total demand.
If you have no means of measuring compressed air, the
following method can be used for analysing losses
through leaks.

This method is recommended when you know the
volume of your storage containers and the volume of the
distribution system.
