BFB04512HHD, BFB04512HD, BFB04512MD, BFB04512VHD specifications

Delta Electronics, a global leader in power management and thermal management solutions, has produced a range of high-performance fans, including the BFB04512VHD, BFB04512MD, BFB04512HD, and BFB04512HHD models. These fans are designed to meet the demanding cooling requirements of various applications, from servers and network equipment to industrial machinery and telecommunications devices.

The BFB04512VHD model features a compact design along with a high airflow capacity, making it ideal for applications where space is limited. It operates at a nominal voltage of 12V and can provide an airflow of up to 45CFM, while maintaining a relatively low noise level of around 32 dBA. This model is equipped with a sleeve bearing system, which ensures smooth operation and longevity. The fan's PWM (Pulse Width Modulation) capability allows for dynamic control of the fan speed, optimizing performance based on the thermal load.

The BFB04512MD stands out for its innovative design that combines high airflow and static pressure capabilities. This makes it suitable for more demanding cooling scenarios where air must be pushed through densely packed components. Like the VHD model, it operates at 12V but is optimized for higher static pressure, making it an excellent choice for servers or systems with restrictive airflow paths.

The BFB04512HD model offers an even higher performance threshold, striking a balance between airflow and noise levels. It excels in energy efficiency, featuring a high-quality motor that minimizes energy consumption while maximizing airflow performance. With its dual ball bearing system, the HD variant offers extended operational life and reliability, making it suitable for continuous operation in critical applications.

Lastly, the BFB04512HHD version takes performance up a notch by focusing on high reliability and ruggedness. This model is built for demanding environments and can operate in a wider temperature range, making it versatile for both commercial and industrial uses. It delivers enhanced airflow while still maintaining low noise levels, ensuring that it meets stringent requirements for environments where thermal control is paramount.

In summary, the Delta Electronics BFB series fans—the BFB04512VHD, BFB04512MD, BFB04512HD, and BFB04512HHD—combine advanced technologies with key characteristics such as high airflow, low noise, versatility, and reliability. These fans are essential for maintaining optimal thermal conditions in a variety of applications across multiple industries, reflecting Delta's commitment to innovation and quality in cooling solutions.
