SANYO DENKI Launches San Ace 40 9RA & 52 9RA DC Fans | Ultra-Low Noise Compact Cooling Fans

SANYO DENKI Launches New San Ace 40 9RA and 52 9RA DC Fans Featuring Industry-Leading Low Noise and Reduced Power Consumption

On May 25, 2026, SANYO DENKI announced the release of two new compact DC cooling fans: the 40 × 40 × 15 mm San Ace 40 9RA and the 52 × 52 × 15 mm San Ace 52 9RA.

Designed for compact, high-density electronic equipment, these new additions to the San Ace lineup deliver an excellent balance of airflow, static pressure, low noise, and energy efficiency. According to SANYO DENKI, the new fans achieve the lowest noise level in their class while significantly reducing power consumption compared with previous models.

Designed for Modern High-Density Equipment

As electronic devices continue to become smaller and more powerful, thermal management has become increasingly important. Cooling fans used in medical systems, industrial automation equipment, power electronics, and communication devices must provide reliable airflow while minimizing noise and energy consumption.

The new San Ace 9RA series addresses these challenges through optimized motor design and aerodynamic improvements.

Typical applications include:

• Medical devices

• Servo amplifiers

• Inverters

• Chip mounters

• Switching power supplies

• Industrial control systems

• Communication equipment

Key Feature 1: Industry-Leading Low Noise

One of the most significant improvements of the new 9RA series is its acoustic performance.

Compared with SANYO DENKI's existing 52 × 52 × 15 mm San Ace 9P models, the new San Ace 52 9RA fans reduce noise levels by up to 6 dB(A).

For equipment manufacturers, lower noise levels offer several advantages:

• Improved user comfort

• Reduced workplace noise

• Better suitability for medical and laboratory environments

• Enhanced product quality perception

This makes the new fans particularly attractive for equipment installed in offices, hospitals, laboratories, and other noise-sensitive environments.

Key Feature 2: Approximately 60% Lower Power Consumption

Energy efficiency is another major highlight of the new series.

Compared with previous models, selected San Ace 9RA fans reduce power consumption by approximately 60% while maintaining effective cooling performance.

Benefits of lower power consumption include:

• Reduced operating costs

• Lower heat generation inside equipment

• Improved overall system efficiency

• Extended battery life in portable applications

As manufacturers increasingly focus on energy-efficient designs, cooling components with lower power requirements are becoming more valuable.

This model provides higher airflow and pressure capability for equipment with greater thermal loads.

Long Service Life for Reliable Operation

All models in the new San Ace 9RA series offer an expected life of 60,000 hours (L10) under continuous operation at rated voltage in a 60°C free-air environment.

This long operating life helps equipment manufacturers reduce maintenance requirements and improve system reliability.

For industrial and medical applications where downtime can be costly, durability remains a key consideration during fan selection.

Industry Trends Reflected by the New 9RA Series

The release of the San Ace 40 9RA and 52 9RA fans highlights several important trends in the cooling industry.

Greater Focus on Noise Reduction

Cooling performance is no longer the only selection criterion. Equipment designers increasingly seek quieter solutions that improve the overall user experience.

Improved Energy Efficiency

Modern electronic systems demand cooling components that can deliver effective thermal performance while consuming less power.

Higher Reliability Requirements

Industrial automation, medical equipment, and power electronics applications require cooling fans capable of operating continuously for many years.

The new 9RA series reflects these evolving market demands by combining low noise, low power consumption, and long service life.

Conclusion

The introduction of the San Ace 40 9RA and San Ace 52 9RA series further strengthens SANYO DENKI's portfolio of high-performance cooling solutions for compact electronic equipment.

By delivering industry-leading low noise levels, significantly reduced power consumption, and long-term reliability, the new 9RA series provides equipment designers with an attractive solution for next-generation thermal management applications.
