Turbine Ventilator Calculator
Note: Calculator is designed specifically for the Tornado range of ventilators. The superior design of the Tornado dome (rotor) will enhance the extraction capacity up to 50% compared to similar designed products. The result of the calculator cannot be compared to other products and may have a negative impact on the effectiveness of the ventilation requirements of the application (refer to sketch).
