Comprehensive Guide to the ASHRAE Duct Fitting Database (Version 6.00.05)
The database is used by HVAC engineers, designers, and contractors to perform accurate pressure loss calculations. These calculations are critical for:
: Engineers can quickly filter fittings by shape (round, rectangular, flat oval), type (elbow, transition, junction), and system zone. Version 6
Using accurate data is critical because standard friction charts designed for sheet metal may not accurately reflect the performance of flexible ducts or fiberglass duct board
Disclaimer: ASHRAE periodically updates the database. Always refer to the official ASHRAE website for the most current version number and errata.
The database is often described as the legacy of (1929–2017), a prominent figure in ASHRAE for over 50 years. Known as the "father" of the ASHRAE Duct Fitting Database, Behls spent decades maintaining it and served as a principal author for the Duct Design chapter in the ASHRAE Handbook—Fundamentals . His goal was to provide engineers with a reliable, standardized way to obtain loss coefficients without manual, error-prone lookups in physical tables. Evolution to Version 6.00.05 Using accurate data is critical because standard friction
Version 60005 was released with enhanced API support. The database is now natively compatible with:
The new search indexing is noticeably faster. You can now filter by “Static pressure recovery” or “High turbulence” flags to isolate problematic fittings instantly.
Ensuring that air reaches all zones as designed.
