A free app for iPhone and iPad that performs pressure loss calculations for 14 select supply, common, and return/exhaust fittings. It is available on the Apple App Store .
ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) is a professional membership organization. It finances the research and development of its standards and software through sales and memberships.
HVAC designers use the database to calculate the pressure drop across specific fittings, such as elbows, tees, transitions, and hoods. Accurately predicting pressure loss ensures that supply and exhaust fans are sized correctly. This prevents under-ventilated spaces, eliminates excessive energy consumption, and reduces aerodynamic noise. Key Features of Version 6.00.05 ashrae duct fitting database 6.00 05 free download

When Leila first saw the file name blinking on the outdated workshop terminal—ASHRAE_Duct_Fitting_Database_6.00_05.zip—she assumed it was just another technical relic. For ten years she’d handled HVAC systems, reading charts and tolerances until they felt like the back of her hand. But she had never seen anyone speak of version 6.00.05 aloud, and the username that uploaded it—Archivist—wasn’t in any of the company logs. It finances the research and development of its
