Sanyo Denki Unveils New 60mm Counter-Rotating DC Cooling Fan

Sanyo Denki announced that it has added a 60-millimeter counter-rotating fan to its line of compact dc cooling fans. Available in 12V S-speed and H-speed models, the new San Ace 60CR measures 60mm (2.36 inches) square by 76mm (2.99 inches) thick, making it suitable for use in servers, storage systems, communications equipment, power supplies, and a variety of industrial machinery.

The San Ace 60CR models are claimed to offer 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 2.26m3/min (an increase of as much as 20% over conventional units according to the company) and static pressure as high as 550Pa. Power consumption is as low as 32.4W, minimum noise generation is 64dB, 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 permit the fans’ rotational speed to be widely and accurately controlled in order to attenuate noise and power consumption.

San Ace 60CR cooling fans are available now, priced at $36 each in small quantities; with a delivery time of 8-12 weeks.
