Sanyo Denki Launches 80 x 80 x 80mm CR Type Cooling Fan

Sanyo Denki has introduced what it claims is the industry’s first counter-rotating cooling fan that measures 80 millimeters (3.15 inches) square by 80mm thick. Available in 12V S-speed and H-speed models, the new San Ace 80CR series dc cooling fans are designed for use in servers, storage systems, communications equipment, power supplies, and a variety of industrial machinery.

The San Ace 80CR models are claimed to have the highest airflow and static pressure capabilities in the industry – made possible by two axially aligned fans rotating counter-clockwise to each other. With newly developed blades and frame that improve overall performance, the result is a maximum airflow of 4.53m³/min and static pressure as high as 520Pa – which is said to be an increase of as much as 68% and 73%, respectively, over conventional units. Power consumption is as low as 43.2W, minimum noise generation of 68dB, and L10 life expectancy is 40,000 hours at 60°C. In addition, the cooling fan is RoHS compliant.

Optional features include tachometer sensor and lock rotor sensor outputs, as well as PWM (pulse-width-modulation) control, which permits the fans’ rotational speed to be widely and accurately controlled in order to attenuate noise and power consumption.

San Ace 80CR cooling fans are available now, priced at $40 each in small quantities; delivery is 8 – 12 weeks.
