The specifically LEPA halo ring increases the cooling performance by allowing more air being absorbed from 4 sides of the frame.
The S-Blade composed with an advanced winglet structure which minimizes the turbulence and stabilizes the airflow; it allows the fan to operate with lower noise level and higher flow rate.
Patented BOL (Barometric Oilless) bearing is a self-lubricating design with Nano materials. The bearing features minimal friction operation; therefore it is quieter than traditional 2 ball-bearing. The special Nano materials intentionally used for high working temperature, with MTBF more than 160,000 hours.
