Report: ASHRAE Duct Fitting Database (Version 6.00.05) The ASHRAE Duct Fitting Database (DFDB) is a specialized engineering software designed to provide loss coefficient data for a wide variety of duct fittings. Version 6.00.05 is the current desktop/cloud iteration, distributed as a single-user annual subscription for cloud-based access. 1. Purpose and Application
The ASHRAE Duct Fitting Database is available through the ASHRAE Bookstore. If you are looking for specific legacy data from version 6.00.05, it is important to note that ASHRAE has transitioned to a web-based subscription model to ensure users always have the most updated coefficients and fitting types.

At the heart of the ASHRAE Duct Fitting Database is the concept of the loss coefficient (C). Every elbow, tee, transition, and hood in a ventilation system introduces turbulence and friction, leading to a drop in total pressure. If an engineer overestimates these losses, they specify a fan that is too large, leading to wasted energy and excessive noise. If they underestimate, the system will fail to deliver the required airflow to the occupied spaces.
Visual Navigation: Features pictorial outlines and an "Explorer" view to help engineers quickly identify the correct fitting based on its physical shape.
