Ashrae Duct Fitting Database Version. 6.00.05 [best] Jun 2026

All coefficients are derived from laboratory testing and peer-reviewed research conducted or vetted by ASHRAE technical committees. Why It Matters for Design

Stop guessing your pressure drops. Get the precision your project deserves. #HVAC #Ductwork #Engineering #BuildingPerformance call to action to point to a specific internal link or download portal? Duct Fitting Database - ASHRAE

Identify the fitting from the database classification. For example, a 90-degree round elbow with a 1.5 radius-to-diameter ratio and no vanes is fitting code . ashrae duct fitting database version. 6.00.05

Run a workshop where each trainee manually calculates ΔP for 10 fittings from the database and compares results to a software output. This builds intuition for when the software may be wrong.

Version 6.00.05 is not merely an update—it is a significant leap forward in HVAC calculation fidelity. Below are its defining characteristics. All coefficients are derived from laboratory testing and

Many design softwares offer a generic “elbow” coefficient of 0.30. Version 6.00.05 will show values ranging from 0.12 (smooth radius, turning vanes) to 1.3 (sharp mitered, no vanes). Use the correct one.

“Missing fitting type from handbook” → Confirm your handbook edition. v6.00.05 does NOT include duct construction data (SMACNA) or acoustics – only loss coefficients. Run a workshop where each trainee manually calculates
