hello hello this is Roberto. and this is the HVAC. channel today we're going to be talking about duck sizer tool all right so let' YouTube·HVAC Easy Math Ductsize - HVAC Duct Sizing and Analysis - Elite Software
Supports cubic feet per minute (CFM) or liters per second (L/s).
A high-quality duct sizer allows you to automate the entire process. Instead of manually referencing ASHRAE tables, you can input airflow (CFM or LPS) and select a method like "Equal Friction" or "Static Regain," and the software instantly calculates the optimal dimensions for round, rectangular, or flat oval ducts. Furthermore, these tools help prevent costly on-site mistakes. Undersized ducts lead to excessive noise and pressure loss, while oversized ducts waste materials and energy. By using a digital tool, you ensure a balanced, code-compliant system that saves time and money from the design phase to the installation.
While the desktop version is standard, there are similar apps available on the Google Play Store. design tools duct sizer version 64 free download exclusive
