This month in Wood Magazine there is an excellent article about sizing the right DC to the right shop. And they make the comment to take off the (2)-4” Y-port and connecting straight to the 6” opening with a 6” main line.
Here is my question… How is a 6” better than a 4”?
If you only have one port open at a time it should stay fairly consistent in velocity all the way to the impeller.
The way I see it…. if you increase the size of the pipe, the velocity (even the though the CFM stays the same) goes down causing the heavy debris to settle in the pipe. What is to be gained by increasing the pipe size? For argument sake if that holds true why not have an 8” pipe?
Love to hear LJ’s response.
Thanx in adavance
