If I have two radial compressors (blowers) in parallel joined by a "Y", each with a capacity to produce 300 cfm, the output at the "Y" connector is the sum of the two, that is. we have 600 cfm? The pressure I know it's the same, but I have been told the flow is added, is this correct? It was thought instead of having a large compressor, he can replace 1 large with two of these smaller, each can flow 300 cfm, put a connection in "Y" will have the resulting flow the sum of them?
I was tough this configuration would result in same additional CFM or the sum of both compressor's CFM and the PSI the same.
The flow potential is 600 cfm... Depending on the Y and piping sizes the actual flow potential will be less due to friction and pressure drop..

Tell me and I forget. Teach me and I remember. Involve me and I learn.
