SANYO DENKI Launches 80 × 80 × 25 mm DC Fan with the Lowest Noise in the Industry
October 25, 2021
New High-Performance Low Noise Series with 7 years L10 Life
SANYO DENKI has developed and launched the 80 × 80 × 25 mm San Ace 80 9RA type DC Fan that features the lowest noise in the industry.(1)
This fan is ideal for cooling medical equipment, AV equipment, and other applications that require particularly quiet operation.

Features
1. Low Noise and Energy Saving
Compared to our current model,(2) noise level has been halved(3) and power consumption has been reduced by 41%.(4)
Moreover, the models with PWM control, which enables the control of fan speed, provide further optimized noise level and efficiency.
2. Long Life
This fan lasts 1.5 times longer than the current model,(2) and is capable of continuous operation for 60,000 hours (approximately 7 years), improving the maintainability.
3. Rich Lineup
The product lineup is available in a wide variety in 12/24/48 voltage, cooling performance, noise level, and PWM control. This allows users to choose the most suitable one for their applications.
(1) Based on our own research as of July 20, 2021, conducted among axial DC fans of equivalent size and cooling performance on the market.
(2) Current model: 80 × 80 × 25 mm San Ace 80 9R type DC Fan (model: 109R0812G401).
(3) A 3 dB(A) decrease in noise level.
(4) For models 9RA0812P4G001 and 9RA0812G4001
