Our fan motors are designed for high performance and efficiency to reduce power consumption and limit self-generated heat.
The bearings and casings are made of metal material, which improves cooling efficiency and reduces the effect of heat on bearing grease.

NMB is a world leader in ball bearing precision technology, manufacturing, and quality. NMB fans use high-quality ball bearings produced in house to design and manufacture long-life, low noise, temperature resistant cooling fans.
NMB fans’ working life is 40,000 hours at an ambient temperature of 60 degrees C.
