Sanyo Denki San Ace 9RF Reversible Flow Fans are bidirectional with approximately equal airflow and static pressure in both directions. This flexibility reduces equipment costs and conserves space by reducing the number of fans necessary to ventilate applications such as mattresses and bedding, houses, beverage vending machines, food display cases, and printers. The rotational speed is manipulated using an external PWM signal decreasing noise and saving energy.
