When designing or upgrading an air duct system, one of the most important factors to consider is static pressure—the resistance the fan must overcome to move air through the ductwork. If the fan you choose cannot handle the required back pressure, the airflow will drop, cooling or ventilation performance will suffer, and energy efficiency will be compromised.
This calculator helps you quickly estimate the static pressure of your ducting system based on its design, so you can select the right fan with confidence. By knowing the true back pressure, you’ll avoid undersized equipment, reduce operating costs, and ensure reliable performance in your factory, warehouse, or workspace.
