Ashrae Duct Fitting Database Version. 6.00.05 Jun 2026

: Designated by letters such as R (Round), Rect (Rectangular), or Flat Oval .

Before the age of cloud computing and integrated BIM (Building Information Modeling), the DFDB was available on CD-ROM. However, version 6.00.05 modernized the platform by introducing via an annual subscription, a shift that dramatically improved accessibility and data management.

The is an indispensable asset for verifying fluid dynamics within forced-air systems. By replacing approximations with verified empirical data, it bridges the gap between conceptual mechanical design and real-world building performance. For engineering firms prioritizing sustainability, acoustics, and system reliability, keeping this version active in their software toolkit is a baseline requirement for success.

: A "Lite" app version exists for field use, allowing engineers to perform quick on-site calculations for a subset of common fittings. 4. Historical Context

Through plugins like Stabicad or Fabrication CADmep , you can map the DFDB version 6.00.05 coefficients directly to your ductwork model. The API typically requires you to point to the .mdb file path. Revit’s "Mechanical Settings" → "Duct Fitting Pressure Drop" can reference the database if an appropriate dynamo script or add-in is used.

: Input ranges were expanded for several fitting types to accommodate larger duct dimensions, including: (Dimensions (Dimensions (Dimensions Carmel Software Data Fixes and Corrections Table Accuracy : Fixed the tables for fittings to ensure they align with official text files. Equation Repair : Corrected equations for the fitting and fixed a copying error for the : Designated by letters such as R (Round),

The ASHRAE Duct Fitting Database, version 6.00.05, is a valuable resource for HVAC designers, engineers, and architects. With its comprehensive library of duct fittings, improved data accuracy, and enhanced user interface, this database is an essential tool for optimizing system performance, reducing energy consumption, and ensuring accurate calculations. As the HVAC industry continues to evolve, the ASHRAE Duct Fitting Database will remain a critical resource for professionals seeking to design efficient, reliable, and cost-effective HVAC systems.

ASHRAE Duct Fitting Database (DFDB) version 6.00.05 is the critical maintenance release of the version 6 software, widely used by HVAC engineers for calculating pressure losses in duct systems

Let’s say you need the loss coefficient for a at 2000 CFM in a 16-inch diameter duct. The is an indispensable asset for verifying fluid

This update introduced critical refinements to the calculation engine and expanded the fitting library.

Fixed mathematical equations for and aligned database tables with source text files for SD5-3 , CD3-3 , and CD3-5 .
