Duct Fitting Loss Calculator Apr 2026

The calculator converts the resistance of a fitting into an equivalent length of straight duct, allowing for easier total pressure calculations.

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 duct fitting loss calculator

By calculating both straight duct friction loss and fitting loss, they provide the total static pressure needed for proper duct design. Key Data Used in Calculations The calculator converts the resistance of a fitting

Proper sizing prevents noisy systems and ensures adequate air delivery to rooms. Key Functions of a Duct Fitting Calculator By

By accurately sizing fans, you prevent over-pressurizing the system, which wastes energy.

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

I can help walk you through the calculation or direct you to a specific tool. Duct Pressure Loss Calculator | Plastec Ventilation
