    Design CFM – Used to properly size the dampers based on a maximum FPM air velocity at the register to avoid air noise and still provide enough throw to heat or cool the space. (Typical acceptable FPM 600 to 800) Max CFM – The maximum amount of air that might move through a damper if it is the only zone open. This assumes the pressure relief is also sized properly (see Pressure Relief below).

  • Duct Sizing Chart

    Dampers on take-off duct runs allow for adjustments of air distribution. In order to maintain velocity, reduce duct size. Never locate ducts at the end of the trunk line run. Last take-off run to be located 12" - 18" from end. Always stagger take-off ducts by 12" to maintain pressure. Use insulated duct or duct board in unheated spaces.
