Officially, the ASHRAE Duct Fitting Database Ver. 6.00.05 is a product available as a cloud-based, one-year subscription. Purchasers receive a one-year subscription for cloud-based access to the database. This subscription model ensures users always have access to the most current data and software updates. It is important to note that this is not a network program; multiple-user licensing is not available for this product.

Accurate calculations prevent over-sizing or under-sizing HVAC fans, directly impacting a building's energy consumption, acoustic performance, and equipment cost. Understanding Version 6.00.05

: This version introduced an integrated database with real-time calculation updates and expanded input ranges for various fittings, such as elbows and transitions.

While these executables (often named AshraeDuct.exe ) allow you to access the full database of 200+ fittings, they are unsupported legacy software . They were designed for 32-bit versions of Windows XP, Vista, 7, and 8, and may not function correctly on modern Windows 10 or 11 systems without compatibility mode. Furthermore, you are not entitled to support from ASHRAE if you use these versions.

In the world of Heating, Ventilation, and Air Conditioning (HVAC), precision is everything. Whether you are a mechanical engineer designing a skyscraper’s ventilation system or an HVAC contractor balancing a residential duct network, one name stands as the gold standard for pressure loss calculations: .

If you need basic functionality without a subscription, ASHRAE offers the app for free.

Here is a clear, factual write-up about this topic, including what the database is, the status of version 60005, and the legitimate ways to obtain it at no cost.

It includes a subset of fittings from the full database for performing pressure loss calculations in both I-P and SI units.
