example, consider a system where the main trunk line is 6" in diameter (representing 615 CFM). When connecting to a machine that requires 395 CFM (4" diameter), you would normally add 615 + 395= 1010 (requiring a 7" duct). However, if the machine can be isolated with a blast gate, then you will not need to add the two air volumes. The

I followed the two lines (thin copper line and the larger/covered in black line) running between outdoor and indoor AC units. If I put my ear next to the larger line, I can clearly hear the humming sound along its length as I move from the outdoor AC unit to the indoor condenser unit. I can also feel vibrations/tremors on this larger line.
