Ningxia Yinchuan W-type H10 sub high efficiency filter, Ningxia Yinchuan plastic frame H10 sub high efficiency filter, Ningxia Yinchuan high wind capacity sub high efficiency filter

Description :

  The W-type H10 sub high efficiency filter is a specialized intermediate filtration device used in air treatment systems, mainly to solve the problem of particle interception in high flow ventilation environments. This sub high efficiency filter is typically used in central air conditioning terminals or fresh air systems in commercial buildings, industrial plants, and hospital cleanrooms. It can effectively remove dust particles with a diameter greater than 1 micron from the air, protect the back-end high-efficiency filter, and extend its service life, ensuring that indoor air quality meets sub high efficiency standards.

  This sub high efficiency filter adopts a sturdy plastic frame structure, and the internal filter material is usually a V-shaped/W-shaped pleated design made of glass fiber or synthetic fiber. This structure greatly increases the effective filtration area, thereby achieving high air volume processing while maintaining low resistance. The implementation standards usually refer to the provisions of GB/T 14295-2019 "Air Filters" regarding high and medium efficiency filters. The atmospheric dust counting efficiency corresponding to H10 level is usually between 90% and 95% (for 0.5 μ m particles), and the frame material is mostly ABS or polypropylene, which has good corrosion resistance and mechanical strength and is suitable for long-term humidity or complex working conditions.

  When selecting a sub high efficiency filter, it is necessary to clearly distinguish its differences from primary filters and HEPA high-efficiency filters: primary filters only intercept large particles, with low resistance but poor accuracy; HEPA has extremely high precision but high resistance and cost; The W-type H10 sub high efficiency filter falls between the two and is suitable for places with high air quality requirements but no need to reach sterile levels. If the on-site space is limited and there is a huge demand for air volume, W-shaped structural design has more advantages than flat plate design. Not suitable for environments containing a large amount of oily mist or corrosive gases. Special oil mist filters or chemical filters should be used for such working conditions.

  When installing a sub high efficiency filter, it is necessary to ensure that the airflow direction is consistent with the box identification, and the sealing strip needs to be tightened 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 increases to the final resistance (usually twice the initial resistance), it should be replaced in a timely manner. Due to the uncleanable W-shaped filter material, it will be scrapped and replaced directly after blockage. Common faults include frame deformation leading to air leakage or filter material damage. If the dust concentration at the air outlet is found to be abnormally high, the machine should be stopped immediately for inspection to prevent unfiltered air from entering the clean area.
