Maximum Recommended Air Flow (SCFM)
Through ANSI Standard Weight Schedule 40 Metal Pipe
•
Flow values in the table below are based on a pressure drop of 10% of the applied pressure per 100 feet of pipe for ⅛", ¼",
⅜", and ½" pipe sizes; and a pressure drop of 5% of the applied pressure per 100 feet of pipe for ¾", 1", 1¼", 2", 2½", 3" pipe
sizes. The table gives recommended flows for pipe sizes at listed pressures and should be used to determine appropriate
piping for air systems.
