5. Compressed Air Lines Sizes

Figuring the correct pipe size for your compressed air system is an important task. 
Pipe that is sized too small can create big pressure losses and reduce operating 

efficiency. 

Many people who plan the piping never consider the fittings or the future. 

FITTINGS: Every pipe fitting creates a certain amount of increased frictional air loss 
that is equal to a specified length of pipe. Any turns in the pipe at fittings, ells, tees, 

and valves increase pressure drops even more. 

FUTURE: Are you planning to add more equipment in the next year or two? Then 
plan for larger piping now. Since the material costs in piping are low compared to 
installation or replacement cost, it’s wise to select pipe of an adequate size. If there 
is any doubt that a pipe size may create a pressure drop, use the next largest size. 
Remember that an oversize pipe compensates for possible scale build-up and 
provides for future expansion of the overall air system. 

Steps to calculating overall piping size for your compressed 
air system:

1.  Determine your air compressor’s maximum CFM.  

2. 

Draw a piping schematic and show all pipe fittings, valves, etc.

 

3.  Measure and write the corresponding lengths of pipe on your schematic, then  

total the length of all straight pipes needed and note that on your schematic.  

4. 

Using TABLE 1 (over page), find your compressor’s CFM number    

 

on the far left column, and then go to the right until you see the column header 
with nearest length in feet to your total pipe length. Find where the  CFM & PIPE 
LENGTH intersect on the chart and it will show the recommended pipe size for 
that length.
