So if I have a VS blower.

And I measure .5" static on the return, and .35" on the supply, total of .85".
And I decrease the static pressure on the return by .2". What will my new supply static be.

19


Don't know if this is right or not, but I'm re-reading Stepen King's Dark Tower series and I'm at the part where everything adds up to 19, so it seemed appropriate.:laughing:

How are you decreasing the return static? Your supply static should remain the same if you don't do anything to the supply distribution system. A VS blower is going to strive to achieve the same cfm no matter what, so you still have the same amount of air going through the same supply ducting system.

Yes it will remain the same in the example I gave.

I was hoping to see others give answers.
