Size duct by airflow: When the application first opens, select the "Duct Sizer (Size By Airflow) option to open the form that allows you to input the total airflow in CFM (L/s) and duct friction loss/velocity to display the resulting duct dimensions. Display equivalent diameter for rec...
Maximum duct diameter at 900 CFM is 12 inches Installing a common duct sized between 9” and 12” is the optimal size range for maintaining a proper velocity across all operating conditions. Trace to the right to select the Dryer Booster and maximum equivalent feet of common duct based on yo...
The SMACNA Duct-U-Lator is a digital version of the classic duct sizing tool. It is used by HVAC professionals to quickly size rectangular, round, and oval duct…
A duct size calculator, commonly known as a ductulator, depends on factors like the size of the space you’re heating or cooling, air flow velocity, friction loss, and available static pressure of the HVAC system.
