: Use Version 60005 for learning and personal projects. For commercial work that requires liability and code compliance, purchase the latest ASHRAE Duct Fitting Database (currently Version 8.0).
While the full desktop and cloud-based version of the database is a requiring an annual subscription, ASHRAE provides a free Lite version for mobile users. 1. Accessing the Official Database
The is a comprehensive tool used by engineers to calculate pressure loss across over 200 types of duct fittings.
Version 60005 refers to a specific build or release of the ASHRAE DFDB software. Over time, ASHRAE has released several versions (e.g., 5.00.00, 6.00.00, 6.00.05). Version 60005 is an older, legacy version of this tool. It is no longer the current release (newer versions include updated fittings, improved interfaces, and bug fixes). However, it remains functional and useful for basic duct design and educational purposes. ashrae duct fitting database version 60005 free
It contains data for more than 200 round, rectangular, and flat oval fittings, including pictorial outlines of each fitting for easy identification.
The ASHRAE Duct Fitting Database (DFDB) is the industry-standard digital reference for HVAC engineers. It is a software application that codifies the findings from ASHRAE Research Project 574, integrating decades of laboratory testing data into an accessible, user-friendly interface. Officially developed and sold by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the database serves as a digital catalog of loss coefficient tables for , covering round, rectangular, and flat-oval shapes.
Ability to save fittings into a project file and export data for further analysis in spreadsheets. How to Access the Database for "Free"
: Includes pictorial outlines for supply, exhaust, and common (supply/return) duct functions. Open the table named FittingLossData
: Space-saving alternatives combining the structural integrity of round ductwork with low-clearance heights.
: Using unlicensed software violates copyright laws and can expose engineering firms to severe financial penalties during compliance audits. Free and Low-Cost Alternatives for Duct Pressure Drop
: While the full paid database has 240+ fittings, the Lite version provides access to a specific subset of common supply, exhaust, and return fittings. Capabilities : Adjust inputs via touch for instant pressure loss results. Supports both I-P and SI units .

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) is pleased to announce that the ASHRAE Duct Fitting Database version 60005 is now available for free download.
Many of the loss coefficient tables found in the database are published in the printed or digital versions of the ASHRAE Handbook. While the Handbook itself is a member benefit or paid resource, many engineering libraries provide free access to it.
Searching for cracked versions, torrents, or free installation files on unauthorized websites poses significant risks:
Before opening, run the file through . Because this is legacy software, some antivirus programs may flag it as a "hacktool" simply because it accesses system registries—but actual malware should be avoided.
