Counter Rotating Fan
Counter Rotating Fan 60mm
60
CRA type
■ Features
High Air Flow and High Static Pressure
Even with a thickness 20 mm less, the maximum air flow of this
fan is approximately 1.1 times and its maximum static pressure
is approximately 1.1 times greater than that of our conventional
counter rotating fan.*
This contributes to space optimization in devices.
* : Specification of Model No. 9CRA0612P6K001. Our conventional counter
rotating fan is 60 x 60 x 76 mm San Ace 60 CRA type, Model No.
9CRA0612P0G001.
