1 Reversible Flow Fan 9RF type Features Reduces the required number of fans Wind direction of the fan can be switched so fewer fans are required. It therefore contributes to reducing equipment costs and saving space. It is suitable for the ventilation of houses, beverage vending machines, food display cases, LED lights, and other places where multiple fans are used to blow air in opposite directions. Controlling of rotational speed and wind direction can be performed by external PWM signals to deliver an appropriate rotational speed, contributing to reducing noise and saving energy. Equivalent cooling performance in both directions It delivers approximately the same airflow and static pressure in both blowing directions, so ventilation management is easy. ø mm Specifications The following nos. have PWM controls and pulse sensors.

(when control voltage is V) Current sink (Isink) = 1 ma max. (when control voltage is 5.25 V) Control terminal voltage = 5.25 V max. (when control terminal is open) 1 T T When control terminal is open, fan rotational speed is the same as when PWM duty cycle is 1%. Either TTL input, open collector or open drain can be used for PWM control input signal.
