Duct Sizer

Designed for HVAC engineers, designers and contractors, the Duct Sizer App has been designed to work in a manner similar to the traditional duct sizing wheels (such as the Trane Ductulator) that have been around for many years and that many engineers are accustomed to.
Designed to allow quick determination of the duct size(s) that will meet the design goal, to make the HVAC designers work easier.

Slide the various scales up and down to determine the desired duct size.

Size based on desired pressure drop per length, velocity or both.
Works for both round and rectangular ducts.

IP and SI units.

Notes:

This application (App) is provided for use by qualified HVAC engineers and designers in the design of air handling systems and is not a substitute for appropriate design services.
