Cooling Fan with Unique Hydro-Dynamic Bearing

The Panasonic UDQFZFH Radial Cooling Fan is designed to deliver remarkable quietness and longevity, thanks to its unique hydro-dynamic bearings. Sized at 40x40x7.7 mm, it operates within a broad temperature range from -30°C to +85°C, emitting less than 32 dBA of noise at 30 cm and weighing approximately 11.5 grams. With a maximum air volume of 0.030 m^3/min and a maximum static pressure of 27 Pa, this fan is an excellent choice for various cooling applications, including automotive, CPE, office automation, and computer equipment.

Panasonic's Cooling Fans offer extended longevity and low operating noise levels. Hydro-dynamic bearing technology enables the fan to function without any physical contact or mechanical wear with the shaft, contributing to its exceptionally low noise output compared to other products available in the market.

The UDQFZFH Cooling Fan stands out for its incredibly low noise level, emitting less than 32 dBA @30 cm, even after prolonged periods of operation due to its non-contact rotation. It boasts an impressive lifespan, providing up to three times more operational hours compared to competing products, with an RPM that experiences minimal decline over time, maintaining a 3% difference in speed.
