What used to take 15 minutes of manual lookups per fitting takes under 30 seconds within the application interface.
: This comprehensive guide covers duct layout, fitting selection, and calculation methods (Equal Friction, Static Regain, etc.). It explicitly details how to use the Duct Fitting Database (DFDB) for accurate system design.
Precision is the foundation of efficient HVAC design. In commercial and industrial buildings, ductwork systems must be accurately sized to ensure proper airflow, minimize energy consumption, and control acoustic levels. For decades, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has provided the definitive resource for calculating pressure losses in duct systems.
Version 6.00.05 includes over , up from approximately 450 in version 5.x. New additions include: ashrae duct fitting database version. 6.00.05

Version 6.00.05 is a maintenance release with disproportionate practical impact: small numerical corrections that reduce uncertainty and enable leaner, more efficient mechanical systems. For professionals focused on energy, cost, and performance fidelity, a short, targeted effort to adopt and validate this release pays off across design, modeling, and operations.

Review the calculated velocity pressure, Reynolds number, loss coefficient ( Cocap C sub o ), and total pressure drop. Best Practices for Accurate Duct Design
While the interface is utilitarian, the value of the data—specifically the updates regarding stacked fitting interference—justifies the cost for serious HVAC designers. If you are tired of guessing on pressure drops or fighting with client specifications during commissioning, this software is your best defense.
User-Friendly InterfaceThe interface allows for quick navigation through the fitting categories. Users can input specific variables like velocity, air density, and fitting dimensions (such as turning radius or angle) to see real-time updates to the loss results. Precision is the foundation of efficient HVAC design
Version 6.00.05 introduces several user-interface enhancements, database corrections, and compatibility patches over older legacy versions. 1. Comprehensive Fitting Library
Engineers select massive, expensive fans that consume excessive electrical power, create acoustic issues, and waste mechanical room space.
Version 6.00.05 of the ASHRAE Duct Fitting Database includes several key features and enhancements, including:
