The values are recorded when the fan speed has stabilized at rated voltage. : Measured after continuous 10 minute operation at rated voltage in clean air, and at ambient temperature of 25C. : Measured in a semi-anechoic chamber with background noise level below 15db (A). The fan is running in free air with the microphone at a distance of one meter from the fan intake. : UL Approve (UL File E175395) : Vibration of acceleration 1.5G and frequency 5~50~5Hz is applied in all 3 directions (X,Y,Z) in cycles of 1 minute each, for a total vibration time of 30 minutes. www.element14.com www.farnell.com www.newark.com Page <1> 15/03/13 V1.0 DC Brushless Fan Air Flow-Static Pressure Characteristics Air Flow Direction : Toward label side.
