So, when they tell you to run 6" ducts as close to the machines as possible before reducing, how should I apply that to both over/under DC at the table saw? Imagine a wye at the far end of the table saw.
1. Should I have the wye immediately split into two 4" runs that go all the way to the over/under ports? (So a 6x4x4 Y and longer runs to the ports.)
or
2. Can I have the wye split into two 6" runs that go as close as possible to the over/under ports and use a reducer to 4" at the last moment? (So a 6x6x6 Y until the ports and then two reducers.)
How would both options impact cfm values?
Merci beaucoup!
