Reversible Flow Fan ■ Features Reduces the required number of fans
・Multiple fans are usually needed to blow air in both directions to ventilate houses, and to cool drink vending machines, food display cases, and printers. ・Wind direction of the fan can be switched so fewer fans are required. ・Reduces equipment costs and saves space. ・Rotational speed is controlled using an external PWM signal to deliver an appropriate rotational speed, reducing noise and saving energy.
Same cooling performance in both directions
・Has approximately the same airflow and static pressure in both blowing directions, so it is easy to control performance.
