NMB fan has the characteristics of high quality, long service life and high reliability. It is an excellent product. NMB axial fan has really achieved a long service life, and its continuous working time is guaranteed to be more than 50000 hours. This working life refers to the working time without deviating from its normal working range, rather than the damage of the general concept. For example, the working current change of NMB fan exceeds 15% of the original design value, so we think it has been damaged, etc. This is completely different from the life marking time of other brands of fans
