Compressed air flow rate has many myths associated with it today. Most people will tell you that a bigger pipe is better and for the most part that is true. However, bigger will cost more! The reason that we sell unique compressed air systems is to offer the customer a choice to choose what suits them best. Size your air system for the tools you will use and the size of your workshop.
For recommendations on system choices and building sizes, please see our CHOOSE A SYSTEM page.
To maximize the flow rate for any of our piping systems, it is best to install your system as a loop. Starting at the air compressor and looping around your shop back to the compressor. This will increase flow rate, decrease pressure drop, and allow smaller line size to be used.
