I was all set to start ducting. My plan was to use a 6" inline vortex fan with a 6" to 4" reducer right at output side of the fan that will be attached to 4" PVC pipe.
I was planning to use 6" ducting elbow from the fan to the hood.
Then the HD guy told me that I was loose too many CFM reducing to 4"
Anyone else doing this? Will I loose too much CFM reducing to 4" form 6"?
6" PVC is not at the big box stores and its kind of... big....
