Note:
* All readings are typical values at rated voltage.
* The noise value is the measured value at the distance of 1 meter from the fan inlet.
* Specifications are subject to change without prior notice.
** “X” in model list can be B, S, and C, meaning Dual Ball Bearing, Sleeve Bearing and 1 Ball + 1 Sleeve Bearing.
