: A "Lite" version of the app is available for iOS, allowing field engineers to perform calculations on a subset of common fittings. Licensing and Integration ashrae duct fitting database version. 6.00.05

The 6.00.05 update specifically focused on expanding fitting options and fixing critical calculation errors from earlier 6.0x builds: New Fittings Added: Right-click DFDB

The primary function of Version 6.00.05 is to quantify the energy losses that occur as air moves through various duct components. Straight ducts exhibit friction losses, but significant pressure drops occur at fittings—where the air changes direction (elbows), changes size (transitions), or enters/exits equipment. Whether you’re a consulting engineer, contractor, or BIM

Let’s break down what you get in this version:

The represents decades of research distilled into a practical engineering tool. It bridges the gap between theoretical fluid dynamics and real-world air distribution design. Whether you’re a consulting engineer, contractor, or BIM specialist, mastering this database will elevate the precision of your pressure drop calculations, reduce energy waste, and ensure quieter, more efficient HVAC systems.
