An Introduction to the 80x80x25mm DC Fan with Ball/Sleeve Bearing

In today's high-performance industrial and electronic sectors, ensuring proficient cooling is not merely beneficial—it is absolutely essential. One of the most effective and trustworthy solutions for thermal regulation is the 80x80x25mm DC fan. Crafted with precision and durability, this compact cooling unit provides an optimal mix of airflow capacity, power efficiency, and acoustic control, making it an indispensable component for a wide variety of applications.

Compact Yet Potent Design

At just 80mm x 80mm x 25mm, this fan possesses a small footprint while delivering remarkable performance. It is perfectly suited for applications where available space is limited, but airflow cannot be compromised. The fan's blades are aerodynamically shaped to maximize air delivery while minimizing turbulence and resistance, which ensures smoother circulation and superior cooling effectiveness. Its compact dimensions allow for integration into tight enclosures and panels without impacting the overall system layout or product size.

High-Efficiency DC-Powered Operation

This fan operates on DC voltage and supports a broad voltage spectrum (from 12V to 48V, depending on the model), which gives system designers great flexibility when integrating it into different voltage platforms. Its low power consumption guarantees energy savings while upholding high reliability and extended operational times. Being DC-powered, these fans are known for their stable function and controllable speed. This model supports Pulse Width Modulation (PWM), which permits dynamic speed adjustments based on real-time temperature data or system loads, optimizing energy use and reducing noise when full-speed operation is not required.

Dual Bearing Choices for Diverse Needs

This design provides two bearing options—ball bearing and sleeve bearing—to accommodate different operational requirements:

• Ball Bearing: Best suited for high-temperature settings or installations that require the fan to function in any orientation. Ball bearings provide a longer operational life and better performance stability over time, making them ideal for industrial and mission-critical systems that demand long-term reliability.

• Sleeve Bearing: Designed for more cost-effective and quieter operation in lower-temperature environments. While offering a shorter lifespan than ball bearings, they are an excellent choice for less demanding applications where acoustic sensitivity is a priority.

This dual-bearing option allows users to select the most appropriate configuration based on their application's unique demands.

Superior Airflow and Pressure Capabilities

With a rated speed varying from 3500 to 6000 RPM, this fan delivers a maximum air movement of up to 77.32 CFM. Such high-performance airflow ensures rapid heat removal, effectively protecting sensitive components from thermal damage or failure. Its static pressure performance is equally impressive, reaching as high as 17.78 mmH₂O depending on the speed setting. This strong pressure capability is particularly advantageous when cooling needs to be delivered through constricted or obstructed pathways.

Low-Noise Operational Performance

Despite its powerful airflow, the fan maintains impressively low acoustic levels, starting from just 37 dBA for lower-speed models up to approximately 48 dBA at maximum output. The acoustic performance is further enhanced by the precise design of the impeller and frame, which work in tandem to minimize vibration and sound resonance. This makes the fan suitable for noise-sensitive environments such as consumer electronics, office equipment, and medical devices.

Durable Construction and Safety Features

Manufactured using UL 94V-0 rated thermal plastic for both its structure and impeller, this fan is both flame-retardant and highly durable. Its robust build quality allows it to endure wide operating temperatures, typically from -10°C to +70°C. The fan is also safeguarded with multiple integrated protections:

• Auto-Restart: Ensures the fan resumes functioning automatically after a power interruption.

• Reverse Polarity Protection: Prevents damage in the event of an incorrect power connection.

• Impedance Protection: Guards against overheating by limiting motor current if there is a mechanical blockage.

• FG and RD Signal Support: Enables advanced monitoring of the fan's status and fault detection for integration into intelligent systems.

Such features contribute to the fan's long service life and overall reliability.

Wide Application Versatility

The 80x80x25mm DC fan is widely used across numerous industries and products, including:

• Consumer Electronics: Desktop computers, gaming systems, and home appliances.

• Industrial Equipment: Inverter cabinets, automation controllers, and power units.

• Medical Devices: Diagnostic equipment, monitoring systems, and ventilators.

• Telecommunication Systems: Routers, servers, switches, and base stations.

• Automotive Electronics: Battery cooling, in-cabin ventilation, and infotainment units.

Its universal design, combined with customizable bearing systems and voltage options, makes it a one-size-fits-many cooling solution.

Simple Installation and Integration

With standard mounting hole dimensions and clear mechanical diagrams provided, integrating this fan into new or existing designs is a straightforward process. The four-corner mounting system ensures secure attachment and resistance to vibration, while the lead wire configuration adheres to UL standards for safe electrical connections.

Conclusion

The 80x80x25mm DC fan with a choice of ball or sleeve bearings is more than just a compact cooling component—it is a smart, efficient, and durable solution for contemporary thermal management challenges. Its combination of powerful airflow, customizable features, low noise output, and robust protection systems ensures it meets the evolving demands of today's electronic and industrial applications. Whether your system requires long-term dependability, quiet operation, or high airflow in a confined space, this fan delivers exceptional performance with proven results.
