Cooling that can run in reverse?
Yes, you heard it right!
In high-density servers, communication cabinets, and industrial equipment, heat dissipation has long been a performance bottleneck:
❌ Excessive fans → Large space occupation
❌ High-density environments → Limited air volume
❌ High heat loads → Difficult temperature control
The Sanyo San Ace Counter-Rotating Dual-Fan is a high-performance cooling fan. Its unique design enables a single fan to achieve the cooling efficiency of two conventional fans.
Working Principle:
The counter-rotating dual-fan consists of two sets of blades. The front and rear blade assemblies rotate in opposite directions along the same axis. By altering air flow angles and pressure differences, it effectively suppresses eddy currents and air flow losses. This creates a "duct pressurization" effect within a limited thickness, resulting in higher static pressure output and improved air flow stability.
Key Advantages:
1、Enhanced Airflow & Static Pressure:
Compared with standard single fans, it boosts maximum airflow by 51% and maximum static pressure by 44%. It easily penetrates high-resistance cooling channels, delivering more comprehensive airflow coverage.
2、Energy-Saving & Low-Noise Operation:
Equipped with PWM speed control, it automatically reduces rotational speed during light or no-load operation. This not only extends fan lifespan, but also significantly lowers noise levels and power consumption.
Product Features:
（1）Premium Materials:
Constructed with eco-friendly, flame-retardant PBT UL 94V-0 material, ensuring excellent fire resistance and durability.
（2）Long Service Life:
Adopts dual ball bearings, offering a lifespan of 30,000 to 70,000 hours and operating reliably within a temperature range of -20℃ to +70℃.
Typical Model Specifications:
Take the model 9CRA0612P6K001 as an example:
Current: 3.1A
Power: 37.2W
Rotational Speed: 18,300 RPM
Airflow: 80.5 CFM
Static Pressure: 1,130 Pa
Noise Level: 73 dB
Application Fields:
Widely used in high-heat-demand applications such as servers, power supply units, and communication equipment.
It effectively meets the cooling requirements of these devices in high-density installation environments.
