150mm High Airflow DC axial Fan Brushless Cooling

Unleashing Superior Cooling Performance: The 150mm High-Airflow DC Axial Fan

In the world of advanced electronics and high-power industrial machinery, effective thermal management is not just a feature—it is the cornerstone of reliability, longevity, and peak performance. The accumulation of heat is the silent enemy of electronic components, leading to reduced efficiency, premature failure, and costly downtime.

Addressing this critical need is our robust 150mm High-Airflow DC Axial Fan, an engineering marvel designed to deliver uncompromising cooling performance in the most demanding environments. This DC axial fan is a powerhouse of airflow, built with industrial-grade components to provide a dependable solution for a vast array of applications, from crowded server racks to heavy-duty manufacturing equipment.

Engineered for Maximum Airflow and Pressure

The primary function of a DC axial fan is to move air, and this 150mm axial fan excels at this task. It is engineered to generate a formidable airflow, ensuring that heat is rapidly and efficiently dissipated from critical components. The fan is available in several configurations, including 12V, 24V, and 48V models, to seamlessly integrate into various system architectures.

At its peak performance, typically seen in the 24V and 48V high-speed variants, this DC axial fan can achieve a remarkable maximum airflow of 278 cubic feet per minute (CFM), which translates to approximately 7.8 cubic meters of air moved every minute. This high volume of airflow is essential for cooling densely packed enclosures, large heat sinks, and systems that generate a significant thermal load.

However, raw airflow is only part of the equation. In many real-world applications, air needs to be forced through restrictive pathways, such as filters, grilles, or tightly spaced components. This requires high static pressure. This fan delivers an impressive maximum static pressure of 35.3 mmH₂O (or 1.4 inches H₂O). This capability ensures that the fan maintains consistent and effective airflow even in high-impedance environments, overcoming back pressure to cool components deep within an enclosure.

The provided P&Q (Pressure vs. Airflow) performance curve illustrates the fan’s dynamic capabilities. It showcases the inverse relationship between airflow and static pressure for different operational speeds (e.g., 4800, 4000, and 3000 RPM). This data is invaluable for engineers, allowing them to precisely match the fan’s performance to their system’s specific impedance characteristics, guaranteeing optimal cooling under all operating conditions. Whether the application requires maximum air volume in an open environment or high-pressure airflow through a constrained space, this fan is engineered to deliver.

Robust Construction for Unmatched Durability

Performance is meaningless without reliability. This 150mm DC axial fan is constructed to withstand the rigors of continuous operation in harsh industrial and commercial settings. Its physical design is a testament to its durability.

• Dimensions and Materials: With a standard frame size of 150 x 150 mm and a thickness of 51 mm, it offers a substantial profile designed for high-output cooling. The frame and the seven-bladed impeller are crafted from high-quality Thermal Plastic with a UL 94V-0 rating. This classification signifies that the material is flame-retardant, providing a critical safety feature that prevents the spread of fire in the event of a catastrophic electronic failure.
• Advanced Bearing System: At the heart of the DC axial fan’s rotational assembly is a dual ball bearing system. Compared to inferior sleeve bearings, dual ball bearings offer significantly higher durability, a longer operational lifespan (often exceeding 50,000 hours), and a wider tolerance for high temperatures. This superior bearing system also allows the fan to be mounted in any orientation—vertical, horizontal, or angled—without compromising its performance or longevity, offering maximum installation flexibility.
• Solid Build: Weighing in at 635 grams, the DC axial fan’s substantial weight reflects its solid construction, from the powerful motor to the reinforced frame, ensuring stability and minimizing vibration during high-speed operation.

Reliability and Protection Features

To ensure the integrity of both the fan and the system it protects, this unit is equipped with a suite of built-in protection mechanisms.

• Wide Operating Voltage: The DC axial fan is designed to operate reliably even with fluctuations in the power supply. For instance, the 24V model has a wide operational voltage range of 14.0V to 27.6V, ensuring consistent performance.
• Motor Protection: It incorporates impedance protection, which safeguards the motor from burnout if the blades are blocked or stalled. It also features reverse polarity protection, which prevents permanent damage to the fan’s sensitive electronics if the power leads are accidentally connected incorrectly during installation—a simple mistake that could otherwise destroy a lesser fan.
• Environmental Tolerance: This DC axial fan is built to thrive where others might fail. It boasts a wide operating temperature range of -10°C to +70°C and an even broader storage temperature range of -40°C to +80°C. This makes it an ideal choice for unconditioned environments, from hot factory floors to outdoor telecommunications enclosures.

Versatility for Diverse Applications

The combination of high performance, rugged construction, and multiple voltage and speed options makes this 150mm axial fan an incredibly versatile cooling solution. Its applications span numerous industries:

• IT and Data Centers: Perfect for cooling rack-mounted servers, network switches, and large data storage arrays where maintaining a stable temperature is paramount.
• Industrial Automation: Ideal for cooling motor controllers, power inverters, PLCs, and enclosed control cabinets on the factory floor.
• Telecommunications: Provides essential cooling for base stations, power amplifiers, and other equipment housed in indoor or outdoor cabinets.
• Welding and Manufacturing: Reliably cools high-power welding machines and other industrial equipment that generate extreme heat.
• High-End Electronics and DIY Projects: An excellent choice for custom computer builds, large audiovisual systems, and any high-stakes DIY project requiring serious ventilation.

In conclusion, this 150mm High-Airflow DC Axial Fan is more than just a component; it’s an investment in the stability and longevity of your critical systems. By combining exceptional airflow and static pressure with a rugged, safety-rated construction and a highly reliable dual ball bearing system, it offers a premier thermal management solution. It is engineered to perform, built to last, and designed to protect, ensuring that your equipment runs cooler, longer, and more efficiently.
