What factors affect the efficiency of air suction filter

The dual impact of particle diameter and type on Air Suction Filter efficiency
Particle diameter is the core factor affecting the efficiency of Air Suction Filter. Studies have shown that when the particle diameter is smaller, these particles are more likely to be deposited on the filter fiber due to the dominant diffusion effect. However, as the particle size increases, the diffusion effect gradually weakens, while the interception and inertial effects increase accordingly. For particles with a diameter of about 0.3 microns, the filtration efficiency of the filter often reaches the lowest point. This phenomenon is particularly prominent during the filtration process of PM2.5 (particle diameter ≤ 2.5 microns). By using advanced filter materials and precise manufacturing processes, Ningbo Sono has significantly improved the Air Suction Filter's filtration efficiency for tiny particles, ensuring excellent performance in a variety of application environments.
The type of particles also has a significant impact on filtration efficiency. Solid particles usually have higher filtration efficiency due to their significant agglomeration phenomenon and charge effect. In comparison, the filtration efficiency of liquid particles is relatively low. In view of this characteristic, Ningbo Sonuo's Air Suction Filter has been specifically optimized during the design process to ensure that it can efficiently handle solid and liquid particles, thereby maintaining excellent filtration performance under various working conditions.

Optimized balance between fiber thickness and filtration speed
Fiber thickness is another key factor affecting the efficiency of Air Suction Filter. Generally speaking, the reduction of fiber diameter helps to improve the collection efficiency, but it is followed by the increase of filter resistance. During the research and development process, Ningbo Sonuo achieved the best balance between filtration efficiency and resistance by precisely controlling the thickness of the fibers. At the same time, the impact of filtration speed on efficiency cannot be ignored. Too fast a filtration speed will increase the probability of dust penetrating the filter material, while too slow a filtration speed will lead to an increase in system energy consumption. Therefore, Ningbo Sono's Air Suction Filter fully considers the relationship between filtration speed and efficiency when designing, and ensures that efficient filtration performance is maintained within a suitable filtration speed range through reasonable design.

Collaborative optimization of air resistance and wind speed
Air resistance is the resistance produced by airflow when passing through the filter material. Its size is closely related to the fiber density of the filter material and the wind speed of the filter device. Ningbo Sonuo has successfully reduced air resistance and improved the smoothness of air flow through the filter by optimizing the structure and manufacturing process of the filter material. In addition, the impact of wind speed on filtration efficiency cannot be ignored. Under low wind speed conditions, the diffusion of small dust is more obvious, thereby improving the filtration efficiency; while under high wind speed conditions, the probability of dust penetrating the filter material increases significantly, resulting in a reduction in filtration efficiency. Therefore, Ningbo Sono's Air Suction Filter fully considers the synergistic relationship between wind speed and filtration efficiency when designing, and achieves the best balance of high-efficiency filtration and low energy consumption through reasonable wind speed settings.

Comprehensive consideration of temperature and atmospheric pressure
Temperature and atmospheric pressure are also important factors affecting the efficiency of Air Suction Filter. As the ambient temperature increases, the viscosity coefficient of the air decreases, harmful particulate matter spreads to a wider range, and the probability of contact with the filter increases, thereby improving the filtration efficiency. However, excessively high temperatures may cause the material performance of the filter to degrade, affecting its long-term use. Ningbo Sonuo fully considers changes in temperature and atmospheric pressure in product design. Through material selection and structural design, it ensures that the Air Suction Filter can operate stably and maintain efficient filtration performance under different temperature and pressure conditions.
