Ashrae Duct Fitting Database Excel Link · Legit
Depending on the version you purchase, the linking between the DFDB software and Excel can be finicky. It often requires enabling specific Add-Ins or Macros, which can sometimes trip up corporate IT security settings.
Are you still manually hunting for duct loss coefficients? The ASHRAE Duct Fitting Database (DFDB) is the industry gold standard for a reason. Why use it? Precision: 200+ round, rectangular, and flat oval fittings.
: This is a robust, free .xlsm tool from Titus that includes a dropdown menu for ASHRAE fitting codes and calculates pressure loss directly within Excel.

Each fitting has a unique (e.g., "E1-1" for a 90° smooth elbow) and its loss coefficient depends on geometry ratios (e.g., r/D , W/H , angle, area ratios). The official data is maintained by ASHRAE Technical Committee (TC) 5.2 .
