Xianyang Baoji W-type H10 sub high efficiency filter, Xianyang Baoji plastic frame H10 sub high efficiency filter, Xianyang Baoji high air volume sub high efficiency filter

Description :

  The W-type H10 sub high efficiency filter is an air filtration device designed specifically for high air volume ventilation systems, mainly addressing the transitional purification needs between primary and high-efficiency filtration in central air conditioning and industrial cleanrooms. This category is usually installed at the end of the air conditioning unit or at the fresh air inlet to intercept particles larger than 1 micron in the air, effectively extending the service life of the rear HEPA high-efficiency filter and reducing system resistance. Its typical operating conditions include hospital operating room auxiliary areas, electronic factory clean areas, food processing workshops, and centralized air supply systems in large commercial buildings. It can provide stable filtration efficiency while maintaining high breathability, ensuring that indoor air quality meets sub high efficiency standards. It is a key component in the purification system that serves as a bridge between the upper and lower levels.

  The core feature of this specification segment product lies in its unique W-shaped folding structure design, which greatly increases the effective filtering area of the filter material within the limited installation space, thereby significantly reducing head-on wind speed and operating resistance. The frame material is usually made of high-strength engineering plastic (plastic frame), which has excellent corrosion resistance and moisture resistance, and can adapt to high humidity environments without deformation. Imported or high-quality domestic glass fiber filter paper is often used as the filter material, which is fixed with hot melt adhesive or polyurethane sealant to ensure no leakage. The implementation standard refers to GB/T 14295-2019 "Air Filters" and related industry specifications. The atmospheric dust counting efficiency corresponding to H10 level is usually between 90% and 95% (for 0.5 μ m particles). The specific test data needs to be based on third-party testing reports, and the common outer frame size should be adapted to the standard module for easy on-site replacement and maintenance.

  In the selection stage, procurement personnel need to focus on distinguishing the application scenarios of sub high efficiency filters from initial and high-efficiency filters. The W-shaped structure is particularly suitable for situations where high air volume is required but installation depth is limited. If there is ample space and low air volume, a flat plate type can be selected; If the requirement for the removal rate of 0.3 μ m particles is higher than 99.9%, it should be upgraded to a HEPA high-efficiency filter. H10 grade is suitable for environments with high cleanliness requirements but not strictly sterile, such as ordinary clean corridors, packaging rooms, etc. It should be noted that the plastic frame version is lighter and more cost-effective compared to the aluminum frame, but the temperature resistance limit needs to be confirmed in extremely high temperature environments. When selecting, the system's rated air volume, allowable initial resistance, and size matching of installation interfaces should be checked to avoid an increase in fan energy consumption or insufficient air volume due to excessive resistance.

  In terms of installation and maintenance, W-type H10 sub high efficiency filters are usually installed in a drawer or flange style. During installation, it is necessary to ensure that the airflow direction is consistent with the filter identification arrow, and the sealing gasket should be tightly pressed to prevent bypass leakage. In daily maintenance, it is recommended to regularly monitor the pressure difference before and after the filter. When the initial resistance reaches the final resistance (usually twice the initial resistance), the filter element should be replaced in a timely manner. Do not attempt to clean the fiberglass filter paper to avoid damaging the fiber structure and causing a decrease in efficiency. The typical usage cycle depends on the concentration of environmental dust and is generally 3-6 months. Common faults include air leakage caused by frame deformation and efficiency drop caused by filter paper damage. During inspection, it is important to focus on checking the sealing of the frame and the integrity of the filter surface, and establish regular replacement records to ensure the stable operation of the purification system.
