Fan and Airflow Calculator

 

How the Calculator Works

Inputs:

Number of fans, fan size (120mm, 140mm, 200mm), number of intake and exhaust fans, and fan speed (RPM).

 

Calculation:

The airflow is calculated based on the area of the fan (using the fan size in mm) and the RPM to determine the amount of air moved (in cubic feet per minute, CFM).

It compares intake and exhaust airflow to determine whether the system has positive, negative, or neutral air pressure.
