Conclusion
The ASHRAE Duct Fitting Database is the industry gold standard for loss coefficients for HVAC air distribution systems.

The data is published in ASHRAE’s Handbook—Fundamentals (Chapter 34) , but the comprehensive digital database includes over 200 fittings with detailed geometries.
The Risks of Downloading Such Files:
- Data Integrity: You may be using a coefficient that was corrected in 2019 while your PDF reflects 2009.
- Legal Exposure: ASHRAE aggressively protects its intellectual property. Distributing a full database without license violates copyright (Title 17, U.S. Code).
- Professional Liability: If you design a system using a patched, unofficial PDF and the coefficients are wrong, your engineering stamp is at risk.
