SANYO DENKI Launches 92 × 92 × 25 mm DC Fan with the Lowest Noise in the Industry

Oct 25, 2021

New High-Performance Low Noise Series with 7 years L10 Life


SANYO DENKI has developed and launched the 92 × 92 × 25 mm San Ace 92 9RA type DC Fan that features the lowest noise in the industry.(1)
This fan is ideal for cooling medical equipment, measuring instruments, and other applications that require particularly quiet operation.

San Ace 92RA

Features of 9RA type 92 x 25mm DC Fan

1. Low Noise and Energy Saving

Compared to our current model,(2) noise level has been more than halved(3) and power consumption has been reduced by 44%.(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 2 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: 92 × 92 × 25 mm San Ace 92 9A type DC Fan (model: 9A0912G401).

(3) A 4 dB(A) decrease in noise level.

(4) For models 9RA0912P4G001 and 9RA0912G4001
