GFB0412HF, GFB0424HF, GFB0405HHF, GFB0424VHF, GFB0405HF specifications

Delta Electronics has made significant strides in the field of fan technologies, providing efficient, reliable cooling solutions for various applications. Among their popular models are the GFB0412VHF, GFB0412HHF, GFB0424HHF, GFB0405HF, and GFB0424VHF. Each of these fans is designed with precision and innovation in mind, catering to the diverse needs of modern electronic systems.

The GFB0412VHF is a 40mm axial fan primarily designed for high-volume cooling. It operates at a voltage range of 12V, providing optimal airflow while maintaining a compact size suitable for tight spaces. One of its standout features is its high static pressure, making it ideal for applications where air must traverse obstacles, such as heat sinks or ventilation ducts. The fan's longevity is enhanced by its robust ball bearing design, ensuring reliable performance over time.

Similarly, the GFB0412HHF, also featuring a 12V voltage rating, is engineered for applications requiring higher airflow rates. With an increased blade pitch compared to the VHF model, it delivers superior cooling performance without significantly increasing noise levels, making it suitable for noise-sensitive environments like home theater systems and gaming setups.

The GFB0424HHF is tailored for systems needing 24V operation. This model provides increased efficiency and enhanced cooling capabilities, enabling it to effectively manage higher thermal loads. The well-designed motor contributes to reduced energy consumption while still delivering high airflow, making it a prime choice for server rooms and industrial machinery.

Moving on to the GFB0405HF, this 5V model is optimized for applications demanding low power consumption while maintaining sufficient airflow. Its lightweight design is ideal for embedded systems and compact devices, typical in consumer electronics and portable gadgets. Despite its small form factor, it does not compromise on performance, achieving a notable balance of airflow and noise.

Lastly, the GFB0424VHF is also designed for 24V operation but focuses on achieving high static pressure. Its unique blade design and optimized motor enhance cooling efficiency, making it an excellent choice for applications with dense electronic components, such as telecommunication equipment.

Overall, Delta Electronics continues to lead in fan technology with these models, combining innovative design and efficient performance to meet the cooling requirements of various industries.
