Ashrae Duct Fitting Database | Version. 6.00.05

The ASHRAE Duct Fitting Database is not a standalone executable program but a structured data file. However, ASHRAE distributes it with a lightweight viewer/editor (ASHRAE DFDB Viewer, version 6.00.05 compatible). Here’s what you need:

Modern design software (AutoCAD, Revit, TRACE 3D Plus, Trane Duct Designer, and Carrier HAP) often references the DFDB. Version 6.00.05 features a cleaner relational schema, making it easier for developers to query loss coefficients via SQL or REST APIs directly from the database. This means your Building Information Modeling (BIM) workflow can now auto-populate pressure drop calculations without manual coefficient lookups. ashrae duct fitting database version. 6.00.05

: New straight duct entries for round ducts, covering velocity-limited and constant equal friction scenarios. CD3-22 & CD3-23 The ASHRAE Duct Fitting Database is not a

This update focused on expanding fitting options and correcting data errors from previous v6 iterations: : CD11-4 : Round straight duct with constant equal friction. CD11-3 : Round straight duct with velocity limits. CD3-22 & CD3-23 : Flexible elbows with ratios of 1.0 and 1.5. Critical Fixes : Version 6

: Increased limits for parameters like width, height, and length on several common fittings, including Why It Matters for Your Projects ASHRAE Duct Fitting Database provides loss coefficient tables for over 200 round, rectangular, and flat oval fittings . Using this software allows you to: Calculate External Static Pressure (ESP)
