Duct Fitting Loss Calculator Apr 2026

A duct fitting loss calculator is an essential HVAC tool used to determine the pressure drop (resistance) caused by fittings like elbows, tees, transitions, and takeoffs within a duct system. These tools help calculate the total static pressure a fan must overcome to deliver the necessary air volume. Key Functions of a Duct Fitting Calculator

you are calculating (e.g., radius elbow, mitered bend, reducer)? What is your airflow rate (CFM) and duct size ? duct fitting loss calculator

The speed of the air (FPM or m/s), which directly affects friction. A duct fitting loss calculator is an essential

Helps ensure that the total pressure does not exceed the capacity of the air handling unit (AHU). What is your airflow rate (CFM) and duct size

Common tools for this include digital apps from industry leaders like Price Industries or online calculators. If you can tell me:

The volume of air (CFM or L/s) passing through the fitting.
