Vertically installed ducts also should be stabilized by support straps every 6 feet.

What size duct is needed for 1200 CFM?

10” diameter

The higher the cubic feet per minute, the larger the duct you'll need. At 600 CFM, the minimum duct size is 6”. At 900 CFM, the sheet metal ductwork fabrication minimum duct size is 8”. Finally, at 1200 CFM and above, consider a 10” diameter duct or larger.

Does reducing duct size increase pressure?

Undersized Ducts

If your ducts are too small to accommodate the air flowing through them, the pressure increases and backs up in the system. This causes resistance for the blower fan, reducing your HVAC system's efficiency and longevity.
