Features
Equipped with Genuine S-FDB* Bearing
This fan is equipped with genuine S-FDB (SONY Fluid
Dynamic Bearing) made by SONY corporation.
Market Leading Low-Noise
Level
S-FDB technology drastically eliminates the friction between the bearing
and the shaft which makes this fan nearly inaudible to human ears. Additional
suction magnet optimizes the magnetic force balance within the rotor to achieve
absolute silence. To even further achieve the absolute silence, the fan is
equipped with the Linear drive IC for reducing electromagnetic noise.
Outstanding Long Life of
150,00 Hours
Patent Pending "S-FDB" structure allows the fan to last up to
150,000 hours.
Anti-Shock Ability
Conventional ball bearing carries a point
contacting structure for rotation. This gives a point supporting situations and
dropping impact which can damage the ball bearing surface leading to irregular
noise. The S-FDB carries a surface contact mechanism for improved anti-shock
structure, which is 5 times stronger than the conventional ball bearing.
