Reversible fans deliver directional flow, speed control

ORION FANS Series of microcontroller-based, up to IP68-rated, reversible flow fans utilize PWM signals to control fan speed. Devices provide an innovative solution to challenging cooling requirements: speed and airflow direction controlled by one fan without supplementing excess wires or circuitry. Previously, if the designer wanted to achieve two directions of airflow, two fans would be required. Units are suitable for outdoor applications where the device intakes air in one direction, but a periodic reverse flow ensures air pathways do not become clogged with environmental debris. The reversible flow fans are currently available in 120mm and 172mm packages, in 12V, 24V, 48V and 60V versions.
