HVAC Duct Size Calculator For Flexible Ducting Sizing That Optimizes CFM And FPM Air Flow Reduces Pressure Loss And Makes Duct Design Pro Grade For Efficient Home And Commercial HVAC Systems
✔️ Single unit pro-grade tool for duct sizing and pressure control
The ASHRAE Duct Size Calculator is a quick reference tool designed to help sizing for round and rectangular sheet metal duct and flexible duct. It supports English (Inch to Pound) measurements on the front and Metric (International System) on the back, and accounts for three compression rates for flexible duct. This compact black reference helps installers and engineers optimize airflow, reduce pressure loss, and match CFM to FPM in home or commercial HVAC designs.
✅ Quick reference tool for sizing round and rectangular duct and flexible duct at three compression rates
✅ Supports English and metric measurements for fast cross-reference
✅ Designed by ASHRAE Duct Design Committee TC 5.2, compact and portable
✅ Compares sheet metal duct sizes to flexible duct equivalents for accurate planning
✅ Color: black, durable, easy to read in workspaces
