If you have purchased the software and are having trouble installing version 6.00.05, follow these steps:
: Allows inputs for volumetric flow rate, velocity, fluid density, and fitting dimensions.
If you cannot see the 'Loss Coefficients (pdf)' help file, you likely need to install the Adobe Acrobat Reader.
: A mobile application for iPhone and iPad that allows pressure loss calculations for a select subset
The ASHRAE DFDB is an electronic database that allows users to compute the pressure losses of specific duct fittings. Instead of manually cross-referencing tables in the ASHRAE Handbook—Fundamentals , engineers use this software to input design parameters—such as velocity, flow rate, and fitting dimensions—to instantly retrieve loss coefficients ( Cocap C sub o Key Features of the Database ashrae duct fitting database version 60005 free
Features an improved indexing system compared to older 5.xx versions, making it faster to locate complex junction fittings. The Reality of "Free" Downloads
The ASHRAE Duct Fitting Database Version 60005 is not just another software tool; it is the professional standard for duct system analysis. Its comprehensive library, dual-unit flexibility, real-time calculations, and data transparency make it an essential asset for any engineer or designer serious about creating efficient, cost-effective HVAC systems. While the full version requires a paid subscription, the investment ensures access to accurate, up-to-date data directly from the source—a crucial requirement for professional practice.
Avoid random "crack" websites. Instead, search on:
The is a professional software tool, but it is not free for the full version. It is typically available through an annual subscription that provides cloud-based access. However, ASHRAE does offer a free mobile version called the Duct Fitting Database Lite app for iOS devices. Overview: ASHRAE Duct Fitting Database (DFDB) If you have purchased the software and are

The remains a hidden gem for the HVAC community. While it lacks the polish of modern software, its raw data—the loss coefficients derived from decades of laboratory testing—is timeless. For the aspiring engineer, it is a fantastic educational tool. For the professional, it is a nostalgic backup when your license server goes down.
While Version 6.00.05 functions as a standalone tool, the underlying data structures align with major Building Information Modeling (BIM) and computational fluid dynamics (CFD) software. Many modern MEP (Mechanical, Electrical, Plumbing) platforms incorporate these exact ASHRAE dataset tables directly into their calculation engines.
