Unlocking Peak Cooling Power: The 150mm High-Volume DC fan

In the domain of high-power industrial machinery and advanced electronics, efficient thermal control is not merely a feature—it stands as the very foundation of longevity, reliability, and optimal performance. The buildup of heat represents the silent adversary of electronic parts, causing diminished efficiency, premature breakdown, and significant operational downtime.

To address this crucial requirement, we present our powerful 150mm High-Airflow DC fan, a marvel of engineering created to provide uncompromising cooling power in the most challenging situations. This DC fan is a true powerhouse of air movement, built with industrial-strength components to offer a dependable solution for a wide range of applications, from packed server enclosures to heavy-duty industrial equipment.

Engineered for Superior Airflow and Pressure

A DC fan's primary duty is to move air, and this 150mm model performs this task with excellence. It is designed to produce a truly formidable airflow, ensuring heat is swiftly and effectively carried away from vital components. The fan is offered in multiple configurations, including 12V, 24V, and 48V versions, allowing for seamless integration into diverse system designs.

At its highest performance level, typically found in the 24V and 48V high-speed models, this DC fan can produce an exceptional maximum airflow of 278 cubic feet per minute (CFM). This translates to moving approximately 7.8 cubic meters of air every single minute. Such a high volume of air circulation is critical for cooling densely populated enclosures, large-scale heat sinks, and systems that produce a substantial thermal output.

However, raw airflow capacity is only one aspect of performance. In many practical scenarios, air must be pushed through restrictive channels like filters, protective grilles, or tightly arranged components. This demands significant static pressure. This fan provides an outstanding maximum static pressure of 35.3 mmH₂O (1.4 inches H₂O). This strength guarantees the fan maintains consistent, effective airflow even in high-impedance conditions, overcoming back-pressure to cool parts located deep inside an assembly.

The supplied P&Q (Pressure vs. Airflow) performance graph details the fan's dynamic range. It demonstrates the inverse correlation between static pressure and airflow for various operating speeds (e.g., 4800, 4000, and 3000 RPM). This information is invaluable for engineers, enabling them to precisely align the fan's output with their system's unique impedance profile, ensuring optimal cooling in all operational states. Whether the use case calls for maximum air volume in an unrestricted space or high-pressure circulation through a confined area, this fan is engineered to deliver.

Resilient Construction for Unmatched Longevity

High performance is of little value without dependability. This 150mm DC fan is built to endure the demands of continuous use in harsh commercial and industrial environments. Its physical architecture is a clear testament to its durability.

• Dimensions and Materials: With a standard 150 x 150 mm frame and a 51 mm thickness, it has a substantial profile designed for high-capacity cooling. The frame and the seven-bladed impeller are made from top-grade Thermal Plastic with a UL 94V-0 classification. This rating indicates the material is flame-retardant, providing a crucial safety measure that inhibits the spread of fire in case of a major electronic failure.

• Advanced Bearing System: Central to the DC fan's rotational mechanism is a dual ball bearing system. Compared to less robust sleeve bearings, dual ball bearings provide far greater durability, a longer operational life (often over 50,000 hours), and a wider tolerance for high temperatures. This superior bearing configuration also permits the fan to be mounted in any position—vertical, horizontal, or angled—without impacting its performance or lifespan, offering maximum installation flexibility.

• Solid Build: Weighing 635 grams, the fan's considerable mass reflects its solid construction, from its powerful motor to its reinforced frame, ensuring stability and reducing vibration during high-speed use.

Dependability and Protective Features

To guarantee the integrity of both the fan and the system it cools, this unit comes equipped with a series of built-in protective mechanisms.

• Wide Operating Voltage: The DC fan is made to operate reliably despite fluctuations in the power source. As an example, the 24V version has a broad operational voltage range from 14.0V to 27.6V, ensuring steady performance.

• Motor Protection: It includes impedance protection, which shields the motor from burnout if the blades become blocked or stalled. It also has reverse polarity protection, which prevents permanent harm to the fan's delicate electronics if the power wires are mistakenly connected incorrectly during setup—a simple error that could otherwise ruin a less protected fan.

• Environmental Resilience: This DC fan is built to operate where others might falter. It features a wide operating temperature range from -10°C to +70°C and an even more extensive storage temperature range of -40°C to +80°C. This makes it an excellent choice for non-climate-controlled settings, from hot industrial floors to outdoor telecommunication cabinets.

Adaptability for Numerous Applications

The blend of high performance, rugged construction, and various voltage and speed options makes this 150mm fan an incredibly adaptable cooling solution. Its uses span many industries:

• IT and Data Centers: It is perfect for cooling rack-mounted servers, network switches, and large data storage systems where maintaining a stable temperature is essential.

• Industrial Automation: It is ideal for cooling motor controllers, power inverters, PLCs, and enclosed control panels on the factory floor.

• Telecommunications: It provides crucial cooling for base stations, power amplifiers, and other hardware housed in indoor or outdoor enclosures.

• Welding and Manufacturing: It reliably cools high-power welding machines and other industrial tools that produce extreme heat.

• High-End Electronics and DIY Projects: It is an excellent choice for custom computer builds, large audiovisual setups, and any high-stakes DIY project that requires serious ventilation.

In summary, this 150mm High-Airflow DC fan is more than a mere component; it represents an investment in the stability and durability of your critical systems. By uniting exceptional airflow and static pressure with a rugged, safety-certified construction and a highly dependable dual ball bearing system, it provides a premier thermal management solution. It is engineered to perform, built to endure, and designed to protect, ensuring your equipment operates cooler, longer, and more efficiently.
