: Users can save specific fittings into project files that are easily stored or transferred.
"The database is corrupt or not a valid MDB file."
Without accurate fitting coefficients, engineers often rely on arbitrary safety factors.This practice leads to over-sized fans, which increase initial equipment costs and consume unnecessary energy throughout the building's lifecycle.

: Computes pressure losses based on actual fluid dynamics properties rather than static look-up tables.
ASHRAE Duct Fitting Database (DFDB) is a comprehensive professional tool used by engineers to calculate pressure losses in HVAC systems. While the full Version 6.00.05 is typically a paid subscription product , a limited "Lite" version is available for free.
