Introducing a Superior Cooling Solution: The High-Velocity 120x25mm Ball Bearing DC Fan

Within the rigorous domain of electronics and high-output equipment, effective heat regulation is not merely an option, but an absolute requirement. Heat stands as a primary adversary to both operational efficiency and equipment longevity. From densely configured server racks and industrial control enclosures to powerful computing systems, the capability to proficiently exhaust heat directly correlates to enhanced reliability, stability, and a prolonged service life for your valuable assets. This is the precise challenge our advanced 120x120x25mm Brushless DC fan is engineered to meet, delivering exceptional cooling capacity, steadfast dependability, and quiet operation.

Crafted for situations where performance cannot be compromised, this DC fan is designed around a durable dual ball bearing mechanism. In contrast to conventional sleeve bearings, which are susceptible to degradation and have a significantly shorter operational life, ball bearings provide greatly reduced friction and superior endurance. This sophisticated bearing technology guarantees an exceptionally long service life, positioning it as a wise investment for continuous, round-the-clock use in mission-critical applications.

Moreover, the intrinsic nature of ball bearings permits versatile installation in any orientation—be it horizontal, vertical, or angled—without impacting performance or lifespan, a level of flexibility not typically offered by sleeve bearing alternatives.

Unmatched Capability and Adaptability

Central to this DC fan's design is its capacity to move a considerable volume of air. Boasting a maximum airflow rating near 98.87 cubic feet per minute (CFM), it can generate substantial circulation even within confined enclosures, ensuring that vital components get the cooling they demand. This high airflow is matched by a remarkable static pressure, which enables the fan to powerfully push air through dense heat sinks, restrictive filters, and chassis with high impedance.

The adaptability of this DC fan is further demonstrated by its broad selection of available operating voltages, which includes 12V, 24V, and 48V DC models. This provision allows for seamless incorporation into a wide array of systems and power configurations. Whether you are engineering a new system or upgrading an old one, you can select the variant that perfectly aligns with your power specifications. The fan's brushless DC motor technology not only contributes to its extended life but also assures efficient energy usage, with power input adjusted to its operational speed, varying from a minimal 1.8 watts to a potent 4.8 watts.

Engineered for Trustworthiness and Endurance

Dependability is a fundamental element of this fan's architecture. The chassis and impeller are fabricated from high-quality Thermal Plastic (PBT) that carries a UL94V-0 rating, signifying a high degree of fire resistance and self-extinguishing characteristics, which adds a crucial layer of safety. This durable construction allows the fan to function flawlessly over a wide temperature spectrum, from a chilly -10°C to a sweltering 70°C (14°F to 158°F), and within humidity levels from 35% to 85% RH.

To further protect your investment, the DC fan integrates vital safety mechanisms. Onboard motor protection prevents harm from overheating or stall situations, while reverse polarity protection guarantees that an accidental wiring error during installation will not lead to a catastrophic failure. These elements, combined with the long-lasting ball bearings, establish this fan as a truly trustworthy cooling solution.
