Invest the time to learn its hierarchy, integrate it into your software stack, and always cross-check the reference velocity. In the high-stakes world of modern building design, guesswork is a liability—and Version 6.00.05 is your hedge against it.
The ASHRAE Duct Fitting Database is a digital compilation of loss coefficients (C₀ or Loss Coefficient) for hundreds of duct fittings commonly used in commercial, industrial, and residential HVAC systems. Each fitting is meticulously categorized and assigned a unique "Loss Coefficient" based on empirical data, Computational Fluid Dynamics (CFD), and legacy research—primarily from the ASHRAE Research Project 1053-RP and the SMACNA HVAC Systems—Duct Design Manual .

Modern purchasers receive a one-year subscription for web-based access, requiring only an internet connection and a modern browser. Mobile Flexibility: Use the companion Duct Fitting Database Lite app on iOS for quick field calculations. Why It Matters
Version 6.00.05 introduces several user-interface enhancements, database corrections, and compatibility patches over older legacy versions. 1. Comprehensive Fitting Library Each fitting is meticulously categorized and assigned a
Advanced fluid dynamics software supports importing loss coefficients from the DFDB. Ensure you map the correct reference area and velocity index.
By linking pressure loss directly to fan energy consumption, the feature could estimate the annual energy cost savings
Finding a specific fitting among hundreds can be tedious. Version 6.00.05 features an intuitive search tree categorized by fitting type, shape, and function. Users can filter by specific code identifiers (e.g., SD4-1 for a specific supply duct elbow configuration). 3. Flexible Unit Conversion
