Ashrae Duct Fitting Database 2016 New! May 2026

Introduction

1. Expanded Fitting Library: Added over 50 new fittings, including modern compact elbows and high-efficiency turning vanes found in green building designs.
2. Revised Loss Coefficients: Updated (C) values for spiral flat oval (SFO) fittings, reflecting manufacturing improvements.
3. Digital Integration: Launched compatibility with major HVAC design software (e.g., Trane Duct Designer, Elite Software, and AutoCAD plugins).
4. Metric and Imperial Units: Seamless toggling between I-P (inches, CFM) and SI (mm, L/s) units.
5. Better Reynolds Number Correction: Provided more granular adjustments for low-pressure systems (e.g., residential), which suffer from laminar or transitional flow.

Mobile Accessibility: A "Lite" version of the app is available for free on the Apple App Store for field use.
