Automatically updates velocity, velocity pressure, and fitting loss coefficients as you alter dimensions or volumetric flow rates (CFM or L/s).

For mobile users, a "Lite" version of the database is available as an app for iPhone and iPad comparison

To support global engineering teams, version 6.00.05 allows seamless toggling between International System of Units (SI) and Inch-Pound (I-P) units. 5. Data Export Capabilities ashrae duct fitting database version. 6.00.05

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has been a leading authority in the HVAC industry for over a century. One of its most valuable resources is the ASHRAE Duct Fitting Database, a comprehensive collection of duct fitting loss coefficients used to calculate the pressure drop in duct systems. The latest version, ASHRAE Duct Fitting Database Version 6.00.05, is a significant update that offers engineers and designers a more accurate and efficient tool for designing and analyzing duct systems.

: Exported reports from this version provide verifiable documentation for green building certifications (like LEED) and code official reviews.

Fully compatible with 64-bit Windows 10 and Windows 11 environments. ΔP=Co×Vpcap delta cap P equals cap C sub

The ASHRAE Duct Fitting Database Version 6.00.05 is available through ASHRAE’s official bookstore. Purchasers receive a for cloud‑based access. Note that multiple user licensing is not available; this is a single‑user product.
