SANYO DENKI

The Largest Air Flow and Highest Static Pressure of ranked top
The Release of the 40 mm Square x 48 mm Thick Counter Rotating Fans CRA Type
“San Ace 40”

Sanyo Denki Co., Ltd. has developed the 40mm square x 48mm thick DC cooling fan “San Ace 40” CRA type for use in servers, storage systems, communication equipment, industrial equipment, and other applications.
These fans have the PWM speed control function for external fan rotation speed control.
These are the counter rotating fans* that have achieved large air flow and high static pressure.

Features

Large air flow and high static pressure

The fans feature the largest air flow and highest static pressure of ranked top in its size.
Reduced thickness by approx. 14% compared with our conventional products**.
Maximum airflow: increased by approx. 2%
Maximum static pressure: increased by approx. 14%

**Our conventional product is the DC cooling fan:
40 mm square × 56 mm thick fan “San Ace 40” CRA type (9CRA0412J502)

* What is the Counter Rotating Fan ?

Two fans that rotate in counterclockwise directions are placed in the same axial core in front and back, so that the characteristics of airflow and static pressure can be improved. This method is called the counter rotating method, and we call a fan that uses this method a Counter Rotating Fan.
