The ASHRAE Duct Fitting Database is the industry-standard software for calculating pressure loss (friction and dynamic losses) for various HVAC duct fittings. Version 6.00.05 represents a specific legacy release of this tool.

The ASHRAE Duct Fitting Database is a proprietary, paid application. Searching for a "free download" of version 6.00.05 outside of official ASHRAE channels carries significant risks. 1. Security and Malware Risks

If you are a full-time engineering student, ASHRAE offers deep discounts. While they may not give away version 6.00.05 specifically (they push newer versions), many university libraries have an . Ask your librarian if they have a site license that includes the DFDB. Alternatively, professors can request evaluation copies for a semester.

Do you need to calculate pressure drops for a or an entire complex network ?

While not software, the 2021 ASHRAE Fundamentals Handbook (Chapter 34) contains the exact same loss coefficient charts that version 6.00.05 automates. You can find legal PDF versions via your local engineering society or university library. You will do the math manually, but the data is the same.

The ASHRAE Duct Fitting Database is a tool of the trade. Treat it as such. Just as you would not trust a free, cracked multimeter to measure voltage on a live panel, do not trust a cracked database to design an air distribution system. Invest in the legitimate tool, or use the free manual methods. Your reputation—and the indoor air quality of your clients—depends on it.
