How long is high dc fan air volume type?

About the life of the dc fan, you first need to understand a little, JingYang of science and technology in the production of fan are using brushless dc motor, so there is no carbon brush the problem of life, the life of the dc fan is mainly related to bearing


oil bearing life is 20000 hours, the double ball bearing is 50000 hours, the life of a hydraulic bearing life 30000 hours, conditions for room temperature under normal service life forecast


for high air volume type 4010 dc fan, speed fast in theory, will accelerate the wastage of the bearing, but for the wear-resisting of high precision bearings, life actually had little effect
