Combined high-efficiency air filters, also known as high-volume/W-type/V-type filters, can be categorized and described in terms of their design features and applications as follows:
I. Classification
By Structure:
Partitioned Combined High-Efficiency Filter: Internally equipped with partitions to maintain the spacing between pleats of filter media. This design facilitates precise control over the shape and distribution of the filter media, enhancing filtration efficiency.
Non-partitioned Combined High-Efficiency Filter: Compared to partitioned types, the non-partitioned design is more compact, offers a larger dust holding capacity, and boasts a sturdier structure, making it suitable for systems with high airflow volumes and constant/variable airflow rates. The HV-type combined high-efficiency filter is a typical example of this design.
By Frame Material:
The frames of combined high-efficiency filters are made from a variety of materials, including plastic, galvanized steel, aluminum, and stainless steel. The choice of frame material not only affects the overall strength of the filter but also directly correlates to its price and cost.
II. Functions
High-Efficiency Filtration:
Combined high-efficiency air filters exhibit extremely high filtration efficiency for tiny particles in the air, particularly those larger than 0.3μm, achieving an efficiency rate of over 99.99%. This superior filtration performance makes them an ideal choice for purification systems in industries such as pharmaceuticals, biological laboratories, hospital operating rooms, food processing, and cosmetics.
Energy Saving and Cost Reduction:
Compared to conventional filters, combined high-efficiency filters reduce pressure loss during system operation by increasing the filter media area, thereby decreasing energy consumption and operational costs. This energy-saving effect is even more pronounced in high-volume ventilation systems.
Durability and Reliability:
The design of combined high-efficiency filters emphasizes durability and reliability. For instance, the filter media is fully sealed within the frame using adhesive to prevent side leakage. Additionally, the chevron-shaped pleats formed during the bending process of the filter media prevent damage, ensuring long-term stable operation of the filter.
Versatile Applications:
Combined high-efficiency filters are not only suitable for high-precision environments such as cleanrooms, electronic factories, and operating rooms but can also be used in large-volume ventilation facilities like power plants and as pre-filters for ultra-high-efficiency filters. Their wide range of applications underscores their robust adaptability and flexibility.
In conclusion, combined high-efficiency air filters have become an indispensable component of modern air purification systems due to their high filtration performance, energy-saving characteristics, durable and reliable design, and extensive application areas.
