Cooling fans
Features
Keeping quiet over a long lifetime by using a unique hydro-dynamic bearing with non-contact rotation.
Wide operating temperature range (-40 to +105°C). (-40 to +120°C under development)
Noise increase is less than ball bearing fans.
Experiencing problems of increased noise due to the deterioration of cooling fans?

Wide temperature range
Applications: automotive LED headlamps

Extended usage within the car
Example:
- Car navigation
The key to quiet cooling is Panasonic's unique hydro-dynamic bearing (UHDB)

Non-contact rotation results in low noise

Even when our fans are used for a long time, the noise does not increase.
