EFB0405HHA, EFB0405HA, EFB0405MA, EFB0412HHA, EFB0412VHA specifications

The Delta EFB series of fans, including models EFB0412MA, EFB0405HA, EFB0405LA, EFB0412VHA, and EFB0412LA, are designed for a variety of cooling solutions in electronic devices and enclosures. These fans are renowned for their reliability, efficiency, and versatility, making them popular in industries ranging from telecommunications and IT to consumer electronics.

One of the standout features of the EFB0412MA is its compact size, with a 40mm x 40mm x 20mm form factor. This model is equipped with a ball bearing design that ensures longevity and reduces operational noise, which is crucial for applications where sound levels must be kept to a minimum. The EFB0412MA offers a voltage range of 12V and operates at a maximum airflow of 13.5 CFM, promoting effective heat dissipation.

Similarly, the EFB0405HA and EFB0405LA models are characterized by their 40mm x 40mm x 5mm dimensions, making them suitable for tight spaces. The HA model runs on a 5V power supply, while the LA variant features a unique low-noise design, further enhancing its application in noise-sensitive equipment. Both fans deliver impressive airflow rates despite their small size, showcasing Delta's commitment to efficient thermal management.

The EFB0412VHA variant is specifically engineered for high performance, supporting 12V operation with a robust airflow that meets demanding cooling requirements. This model stands out with its high-speed operation but maintains a focus on energy efficiency, aligning with modern standards for sustainability without sacrificing performance.

The EFB0412LA emphasizes low acoustics, making it ideal for applications that require a silent operation. It utilizes advanced engineering technologies to minimize vibrations, creating a still environment while providing adequate cooling.

Overall, the Delta EFB series fans feature advanced technologies such as high-quality bearings, optimized blade shapes for enhanced airflow, and durable construction materials that ensure reliability over time. The combination of low noise profiles, compact designs, and high performance makes the EFB series a top choice for designers requiring effective cooling solutions in various applications.
