  • To keep "quiet" for long time by Unique Hydro Dynamic Bearing with Non-contact rotation
  • To be able to use in wide operating temperature range (-40 to +105 deg.C) (Under development to use in wide range -40 to +120℃)
  • Noise increase is less than ball bearing fan

Do you have any problem of noise increase by deterioration of cooling fan?

[For example car LED headlamp]When you want  to use with a wide temperature range. [For example car-navigation]When you want to use quietly a long time in a cabin.

Key of quiet Cooling! " Unique Hydro Dynamic Bearing"(UHDB)

Structure of UHDB

"Non-contact rotation" conduct a low noise

Even if a long use, noise doesn't increase
