CFM stands for cubic feet per minute and refers to the amount of compressed air your tools require to operate continuously.
To determine the CFM, you need to factor in the air consumption of each tool and equipment you plan to use simultaneously. Once you have the total CFM requirement, you can then calculate the appropriate copper pipe size required. Generally, the larger the CFM requirement, the larger the pipe diameter needed to maintain adequate airflow for each tool.
So, when determining your copper pipe size, it’s essential to keep your CFM requirements in mind. A good rule of thumb is to use the pipe size that offers at least 1PSI drop from the compressor’s output to the tool’s inlet to ensure optimal performance. By calculating the CFM requirements of your equipment and selecting the appropriate copper pipe size, you can create a reliable, efficient, and effective compressed air system.
Consulting the Manufacturer’s Recommendations
When it comes to determining the required size of your copper pipe for your air compressor lines, consulting the manufacturer’s recommendations is crucial.
