How is the size ratio of cylinder and air outlet suitable?

1: 2 to 1: 3 is more appropriate. The diameter ratio of air compressor and air outlet is between 1: 2 and 1: 3. This can ensure the stability of the output pressure of the air compressor and meet the flow demand of the air outlet. If higher air pressure and flow rate are needed, consider increasing the number of air compressors and air outlets, and appropriately increasing the diameter ratio.
