Ashrae Duct Fitting Database Version 60005 – Validated & Exclusive

: Fittings and results can be saved into specific project files for easy navigation, storage, and transfer.

The ASHRAE Duct Fitting Database is a comprehensive collection of duct fitting loss coefficients, which are used to calculate the pressure drop in duct systems. The database is a valuable resource for engineers, designers, and contractors who work with heating, ventilation, and air conditioning (HVAC) systems.

The ASHRAE Duct Fitting Database is a comprehensive software package containing loss coefficient data for more than 200 distinct duct fittings. Developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, this tool allows engineers to calculate pressure losses across supply, return, and exhaust systems.

The ASHRAE Duct Fitting Database is a comprehensive digital catalogue of resistance coefficients (K-values) for HVAC duct fittings. It is designed to help engineers calculate the pressure drop caused by fittings in a duct system quickly and accurately. By using the DFDB, engineers can automate pressure-drop calculations, enhance accuracy, and comply with ASHRAE Handbook guidelines.

For engineers looking to ensure their designs are precise in 2026, subscribing to the latest ASHRAE Duct Fitting Database is a necessary step. : Fittings and results can be saved into

A 90° short-radius elbow in a 300 mm round duct might have a K of ~1.2 (example order). At 2 m/s this could add only a few Pascals, but at higher flows the loss rises with velocity-squared; in large systems with many fittings cumulative loss can change fan selection and energy use measurably.

The ASHRAE DFDB simplifies this process by providing the dimensionless loss coefficient ( Cocap C sub o
