📐 Master airflow like a pro — don’t let duct compression slow you down!
The ADI Ductulator is a precision duct size calculator developed by the Air Distribution Institute, incorporating university research on flexible duct compression effects. It quantifies pressure loss at various compression levels (4%, 15%, 30%) and helps HVAC professionals select the optimal duct size to maintain efficient airflow despite real-world installation challenges like bends and sags. Featuring a dual-sided design with a calculator and fitting charts, it’s an essential tool for ensuring proper CFM and FPM in air distribution systems.

This is the most complete Duct Size Calculator available, other than the ASHRAE version. It gives equivalent sizes for any combination of CFM, Velocity and Friction Loss in Round and Rectangular Sheet Metal Duct as well as Flexible Duct at three different compression installations. It is also the only Duct Size Calculator approved for use in the Texas State HVAC License Exam.
