Ashrae Duct Fitting Database Version 60005
You can download Version 60005 directly from the ASHRAE Bookstore or through your licensed DFDB portal. If you use a third-party tool (like Trane Duct Designer or Elite Software ), check with their support team—most major platforms will release a compatibility patch within the next 30 days.
: Includes pictorial outlines for over 200 fittings across supply, exhaust, and common duct functions.
Discuss how the database accounts for air density, temperature, and elevation—settings found in the Global Settings Tab . 4. Key Updates in Version 6.00.05
: Dual-unit functionality allowing seamless switching between I-P (Inch-Pound) and SI (International System) units.
: Allows users to toggle between I-P (Imperial) and SI (Metric) units globally or for individual projects. ashrae duct fitting database version 60005
Enter the dimensions (D, H, W) of the duct and fitting.
Includes over 200 diverse fitting types, spanning round, rectangular, and flat oval geometries.
ASHRAE’s versioning follows a simple but meaningful pattern: . The jump from 60004 to 60005 signals a significant data update , not just bug fixes. In plain English: some of the loss coefficients you used last year are now outdated.

Instead of relying on outdated, static tables, the DFDB provides detailed, graphically represented data that allows engineers to accurately calculate pressure drop across various fitting types in round, rectangular, and flat oval ducts. Key Features of Modern DFDB (Version 6.00.05 and Later)
The latest version of the ASHRAE Duct Fitting Database, version 6.0.0.5, includes several significant updates and improvements. Some of the key features of this version include:
The is an indispensable tool for mechanical engineers, designers, and HVAC technicians. By offering a comprehensive, cloud-based, and graphically aided database of fitting pressure losses, it empowers professionals to design more efficient, reliable, and compliant air distribution systems.
The technical team revisited the regression algorithms for Circular 90-degree Mitered Elbows (CR3) and Conical Tapers (CTJ). Users in early beta testing reported that version 60005 reduces the variance between the database prediction and real-world CFD results by approximately for high-velocity systems (above 2,500 FPM). Discuss how the database accounts for air density,
This article provides a deep dive into the ASHRAE Duct Fitting Database, specifically highlighting the functionality and importance of , its features, and its role in modern HVAC engineering. What is the ASHRAE Duct Fitting Database (DFDB)?
For engineers looking to ensure their designs are precise in 2026, subscribing to the latest ASHRAE Duct Fitting Database is a necessary step.
The provides the data necessary to:
