Rated voltage ………………… This is the necessary voltage to drive the fan. E.g.) 12 VDC, 24 VDC, 48 VDC
Operating voltage range …… The voltage range over which fan operation is guaranteed.
Rated current ………………… The current when the fan is operating at rated voltage (at free air).
Rated input …………………… The power value when the fan is operating at rated voltage (at free air).
Rated speed …………………… The speed when the fan is operating at rated voltage (at free air).
Max. airow ……………………
The maximum airow that the fan can generate during rated operation (measured with our double chamber measuring device).
Airow is the volume of air generated by the fan per unit of time.
Max. static pressure …………
The maximum static pressure value that the fan can produce during rated operation (measured with our double chamber measuring device).
Static pressure indicates a fan's ability to move air against resistance due to the internal structure of the device to which the fan is installed.
SPL ……………………………… SPL stands for Sound Pressure Level. The noise level during the fan's rated operation.
Please refer to the technical material section for the measurement method.
Operating temperature ……… The temperature range over which fan operation is guaranteed (Non- condensing).
Expected life
…………………… Service life hours that 90% of bearings will survive without failing when continuously operated at the rated voltage and 60˚C
temperature. Expected life at 40˚C is for reference only.
