Ashrae Duct Fitting Database Version. 6.00.05 Jun 2026

The reliability of the ASHRAE DFDB rests on a solid technical foundation. Each fitting’s loss coefficient is derived from laboratory testing that conforms to , which establishes uniform methods for testing ducts and fittings to determine their flow resistance.

Field engineers can use the to perform quick pressure loss checks on‑site. The app supports select supply, common, and return/exhaust fittings in both I‑P and SI units, enabling rapid validation of as‑built conditions against design assumptions.

Enter the . Version 6.00.05 represents the latest evolution of this critical engineering tool. This article explores everything you need to know about Version 6.00.05: what it is, why it matters, key features, installation, integration, and best practices for leveraging it in modern HVAC design workflows.

Specialized data for different flow directions. ashrae duct fitting database version. 6.00.05

To support global engineering teams, version 6.00.05 allows seamless toggling between International System of Units (SI) and Inch-Pound (I-P) units. 5. Data Export Capabilities

: It is the standard software for determining External Static Pressure (ESP) required for proper fan and equipment selection.

Using the ASHRAE DFDB Version 6.00.05 is straightforward, even for complex systems: The reliability of the ASHRAE DFDB rests on

The is far more than a simple software release; it is the culmination of decades of research, digital evolution, and direct response to the needs of the HVAC engineering community. By introducing real-time calculations, a cloud-based distribution model, and a host of new and corrected fittings, this version set a new benchmark for the industry.

Instead of just providing the pressure loss for a single selected fitting, this feature would allow you to compare design alternatives automatically. Fitting Alternatives Suggestion:

Many third-party HVAC design and BIM software packages (such as Autodesk Revit or Wrightsoft) build their native duct calculation engines to reference or sync with specific ASHRAE database versions. The app supports select supply, common, and return/exhaust

). The DFDB computes these coefficients precisely based on laboratory-tested data and aerodynamic principles.

: The database includes unique data for supply, exhaust, and common (supply/return) duct functions. 2. Version 6.00.05 Technical Updates
