Designed to halve the number of fans required in applications where air flow both in and out of the enclosure is required, EAO has introduced a new range of bi-directional fans that provide the same high airflow performance in both directions.
Adding to the Sanyo Denki portfolio of DC axial fans the new RF Series comprises two models: Measuring 136mm by 28mm the136RF fan delivers bi-directional airflow of 120m3/hour (71CFM) and static pressure of 102Pa. Its more compact brother – the 92RF – measures only 92mm round by 38mm thick yet delivers a bi-directional airflow of 72m3/hour (42CFM) with a static pressure of 156Pa.
Designed for maximum energy and acoustic efficiency the 136RF and 92RF bi-directional fans feature a precision dual ball bearing chassis and built-in PWM control that enables a single wire to control both the air flow direction and the speed of the fan. With a rated life time of 70,000 hours at 40°C they deliver reliable unattended operation in applications ranging from ventilation systems to cold drink vending machines and food display cases and operate at temperatures between -20 to +70°C.
