ASHRAE Duct Fitting Database (DFDB) Version 6.00.05 is a specialized engineering tool used to calculate pressure loss in heating, ventilation, and air-conditioning (HVAC) systems. While the full desktop and cloud-based versions typically require a paid annual subscription from , a free "Lite" version is available for mobile devices. Overview of ASHRAE DFDB 6.00.05
The database includes over 350 distinct fitting families, subdivided into thousands of specific configurations. Categories include: ashrae duct fitting database 6.00 05 free download

The is a critical resource for HVAC engineers, providing the precise loss coefficient data needed to calculate pressure drops in air distribution systems. Version 6.00.05 is one of the more recognized legacy versions of this standalone software, though ASHRAE has since transitioned to cloud-based and updated application formats.
