An Introduction to the 80x80x25mm DC Fan with Ball Bearing (12-48V)

In advanced electronic and industrial environments, the management of heat through consistent airflow is paramount to the longevity and effectiveness of equipment. The 80x80x25mm DC fan, equipped with a durable ball bearing system, provides a dependable and resilient cooling solution engineered to satisfy the requirements of diverse applications, from industrial control hardware to telecommunications and high-power electronics.

Compact and Adaptable Design

With a small form factor measuring just 80mm x 80mm x 25mm, this DC fan is designed for integration into space-limited installations without sacrificing cooling capability. Its square shape and minimal weight of only 72 grams guarantee straightforward placement in enclosures, panels, or any setup that demands regular cooling within tight confines. The fan is constructed from high-grade UL 94V-0 thermal plastic for its frame and impeller, a flame-resistant material that enhances safety while ensuring durability across various environmental conditions.

Broad Voltage Range Support (12V, 24V, 48V)

This fan is offered in configurations that are compatible with three separate rated voltages—12V, 24V, and 48V DC. Each version supports a wide operational voltage spectrum:

• 12V Models: 7.0–13.8 V

• 24V Models: 14.0–27.6 V

• 48V Models: 28.0–56.0 V

This extensive voltage adaptability ensures stable functioning even with fluctuating power supplies, making it highly suitable for mission-critical systems where reliability is a top priority.

Advanced Ball Bearing Mechanism

Outfitted with a ball bearing system, this fan provides extended performance with diminished friction and less wear over time when compared to sleeve-bearing alternatives. The ball bearings ensure dependable operation at both elevated and low temperatures and support any mounting orientation—horizontal, vertical, or angled—without impacting performance or lifespan. This makes the DC fan especially well-suited for continuous operation in challenging settings.

Impressive Airflow and Static Pressure

Cooling effectiveness is where this fan truly shines. Depending on the specific model, it achieves rated speeds from 5000 to 8200 RPM. This allows for a maximum air displacement of up to 79.05 CFM and a static pressure as high as 20.35 mmH₂O. These strong airflow rates guarantee efficient cooling of powerful hardware, circuit boards, or densely packed enclosures. Even at lower speeds, the fan delivers a respectable 48.2 CFM, ensuring effective thermal management with lower power draw and reduced acoustic output.

Noise Optimization

Acoustic levels range from a mere 39 dBA to 51 dBA, based on the voltage and speed settings. This makes the fan appropriate for environments where sound sensitivity is a factor, such as office equipment, medical devices, or audio-visual hardware, while still providing significant airflow.

Power Efficiency

Energy consumption ranges from just 3.4 W to 8.4 W, depending on the chosen voltage and speed. Low-current models are particularly well-suited for energy-conscious applications or systems that run on battery power. The fan also incorporates auto-restart and reverse polarity protection, features that safeguard both the fan and the host device from electrical faults and unexpected power losses.

Environmental and Safety Certifications

This fan is constructed to operate within broad temperature and humidity parameters, from -10°C to +70°C and 35% to 85% RH respectively. It also features impedance protection and supports advanced options like Frequency Generator (FG) signal output for monitoring, Rotation Detection (RD) for operational feedback, Ingress Protection (IP) for enhanced dust and moisture resistance, and Pulse Width Modulation (PWM) for precise speed control. These features make it a preferred choice for intelligent systems that require real-time monitoring and automated fan speed adjustments.

Typical Applications

The 80x80x25mm DC fan is versatile and appropriate for a wide variety of uses, including but not limited to:

• Industrial Automation: Keeping control cabinets and PLC units properly cooled.

• Telecom and Network Hardware: Maintaining airflow in routers, servers, switches, and base stations.

• Power Supplies and Inverters: Averting thermal shutdowns in power electronics.

• Medical Instruments: Providing quiet, dependable airflow in diagnostic and treatment apparatus.

• Consumer Electronics: Cooling for desktop computers, gaming consoles, and media centers.

Conclusion

The 80x80x25mm DC Fan with a ball bearing system represents an ideal balance of compact design, powerful performance, and long-term dependability. Whether you are cooling electronic enclosures, enhancing the airflow of embedded systems, or managing thermal regulation in industrial cabinets, this fan offers outstanding value and versatility. With its wide voltage support, intelligent control options, and resilient ball bearing mechanism, it is the perfect cooling solution for professionals who need effective thermal management in demanding environments.
