When choosing industrial-grade DC Fans, high air pressure and high air volume are two key considerations, each suitable for different industrial scenarios.
Applicable scenarios: When the heat dissipation channels of industrial equipment are relatively narrow and the air circulation resistance is large, such as some compact electrical control cabinets and precision instruments with complex internal structures, fans need to have sufficient pressure to push the air through these obstructions. At this time, high-pressure fans become particularly important. In addition, in cases where air needs to be transported over long distances or through multiple layers of filters, such as the ventilation systems of large industrial ovens or ventilation equipment in clean workshops equipped with high-efficiency filtration devices, high-pressure fans can overcome the resistance of pipelines and filters, ensuring the effective circulation of air.
Advantage: The high-pressure fan can maintain a stable airflow output even when overcoming significant resistance, ensuring effective heat dissipation or ventilation. It can enable the air to form effective convection within a limited space, avoiding problems such as local overheating or gas accumulation. For instance, in high-frequency switching power supply equipment, high-pressure fans can precisely deliver cold air to the vicinity of heat-generating components, achieving excellent heat dissipation even in confined Spaces. This helps enhance the stability and reliability of the equipment and extend its service life.
Selection considerations: In addition to paying attention to the wind pressure value of the fan, it is also necessary to consider the fan's size, rotational speed, noise level, and compatibility with the equipment, etc. Generally speaking, for fans of the same size, the higher the rotational speed, the greater the wind pressure, but at the same time, the noise may also be louder. Therefore, under the premise of meeting the wind pressure requirements, products with lower noise should be selected as much as possible to meet the requirements of the working environment.
High air volume fan
Applicable scenarios: For some open or large-space industrial equipment and places, such as large server rooms, open industrial production workshops, etc., where rapid and large-scale air exchange is required to lower the overall temperature or improve air quality, high-volume fans are more suitable. In these scenarios, the paths for air circulation are relatively smooth with few obstacles. The main requirement is to be able to transport a large amount of air within a unit of time.
Advantages: The high-volume fan can quickly remove the heat and stale air in the equipment or space, improving the heat dissipation efficiency and ventilation effect. For instance, in large data centers, the simultaneous operation of a large number of servers generates a huge amount of heat. High-volume fans can quickly expel the hot air from the computer room and introduce cold air, maintaining the temperature inside the computer room within an appropriate range and ensuring the normal operation of the servers. Meanwhile, high-volume fans also help reduce indoor humidity and improve the comfort of the working environment.
Selection considerations: When selecting, the required air volume should be determined based on the actual space size and heat dissipation requirements. In addition, high air volume fans usually have a large power and relatively high energy consumption. Therefore, the power supply and operating costs of the equipment should be taken into consideration. At the same time, attention should also be paid to the noise level of the fan. Try to choose products that can maintain a low noise level even at high air volume to reduce the impact on the working environment.
When choosing industrial-grade DC fans, it is not advisable to simply believe that high air pressure or high air volume is necessarily better. Instead, a comprehensive judgment should be made based on specific industrial application scenarios, the structural features of the equipment, and actual heat dissipation or ventilation requirements to rationally select fans with high air pressure or high air volume, so as to achieve the best usage effect and economic benefits.
