The ADI, Air Distribution Institute, brings you a very user friendly and simple Ductulator. Our Ductulator utilizes slider bars as well as input boxes to allow for quick and easy sizing of duct work. You can also input the CFM’s for total airflow, aspect ratio, and either friction loss or velocity of air to compute velocity and friction loss along with the dimensions of the duct work. This can also be done in reverse to calculate duct friction loss. Data can be inputted and displayed in imperial or metric units.

Our app also shows the benefits of steel duct over flex duct.

ADI’s app is the only duct sizing utility that also includes the convenience of a built in flashlight along with addresses, emails, and phone numbers to all the ADI members.

The ADI - Air Distribution Institute, was formed in 1947 to promote the use of fabricated steel duct pipe and fittings for air distribution products. Today the alliance of ADI member companies produce steel duct pipe and fittings designed to efficiently deliver conditioned air in your home and office. ADI sponsors independent third party research to accurately substantiate the superior benefits of Steel Air Distribution Systems.
