Ashrae Duct Fitting Database Version 60 Free Download Full Install _top_ Jun 2026

While not the interactive software, the raw data for duct fitting loss coefficients is available in the ASHRAE Handbook—Fundamentals (Chapter 21: Duct Design). Many university libraries provide free digital access to the ASHRAE Handbooks for students.

The core mission of the database is to provide HVAC engineers with instant access to a comprehensive digital catalog of loss coefficients, or , for hundreds of standard and custom duct fittings. Instead of manually searching through dense tables, you simply input your duct velocity and fitting type, and the software instantly computes the pressure drop using the fundamental formula ∆P = K·½ρV² . This efficiency helps ensure that fan sizing and system performance predictions are accurate and reliable.

: Allows users to quickly find fittings by ASHRAE code or visual category.
