Reversible Flow Fan
■ Features
Reduces the required number of fans

・Multiple fans are usually needed to blow air in both directions to
ventilate houses, beverage 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.
