Ashrae Duct Fitting Database Version. 6.00.05 [updated] Jun 2026

Enter the physical parameters, such as duct width ( ), height ( ), diameter ( ), or turning radius (

The is a high-precision digital tool designed for HVAC engineers to calculate pressure loss across complex duct networks. Developed by ASHRAE in collaboration with Carmel Software Corporation , this version serves as the industry standard for determining duct fitting loss coefficients (C-factors). Key Features of Version 6.00.05

These changes demonstrate a commitment to not only maintaining the database but actively refining it based on user feedback and emerging data. ashrae duct fitting database version. 6.00.05

ASHRAE DFDB Version 6.00.05 is designed for Windows-based environments. It is typically distributed as a standalone desktop application. While newer versions or web-based iterations may exist, 6.00.05 is often preferred in specific engineering firms for its stability and consistency with legacy project data. Conclusion

Do you need assistance mapping a to its correct ASHRAE fitting code? Enter the physical parameters, such as duct width

Quick calculations for converging, diverging, and straight-through airflow patterns.

To help you get the most out of this software, could you share a bit more context? Let me know: ASHRAE DFDB Version 6

Let’s say you need the loss coefficient for a at 2000 CFM in a 16-inch diameter duct.
