Ashrae Duct Fitting Database Version 60005 -

Where (P_v) is the velocity pressure. Version 60005 is the latest iteration of this database, released to support ASHRAE’s Fundamentals Handbook and HVAC Duct Construction Standards .

As HVAC systems become more complex and energy efficiency standards rise, precision in duct design is more critical than ever. The is the industry-standard tool for calculating pressure losses in HVAC systems, and keeping up with its latest iterations—such as the advanced, cloud-based offerings—is essential for engineering professionals.

Most engineers do not open the raw database. Instead:

Where:

The final pressure drop is calculated, enabling the design team to move forward with fan selection. Conclusion

used for complex junction fittings (tees/wyes)

Supply, Exhaust, Common, Junctions, or Transitions Category: Elbows, Tees, Wyes, Entrances, or Outlets Understanding the Math: How Version 6.00.05 Calculates Loss ashrae duct fitting database version 60005

: Includes pictorial outlines and detailed data for a wide range of fittings, such as elbows, tees, and transitions.

For engineers looking to ensure their designs are precise in 2026, subscribing to the latest ASHRAE Duct Fitting Database is a necessary step.

: Fittings can be saved into specific project files that are transferable between users. Access & Licensing : Primarily available as an annual cloud-based subscription : It is strictly a single-user product ; multiple-user licensing is not currently offered. Mobile Support Where (P_v) is the velocity pressure

Users can enter specific dimensions and airflow data, and the software calculates the precise pressure loss, often including velocity calculations. Why Version 6.00.05 Matters in 2026

Double-check that your global settings are correctly toggled to either IP (Inch-Pound) or SI (International System) units before copying values over to design documents.
