Medium efficiency non-woven fabric filter bag structure for efficient dust removal, suitable for air conditioning and ventilation systems

Description :

  Medium efficiency filters are key components in air purification systems, mainly used to capture particulate pollutants of 1-5 microns. It is usually installed after the primary filter and before the high-efficiency filter to protect the back-end high-efficiency filter and extend its service life. This product is widely used in places with moderate air quality requirements such as central air conditioning ventilation systems, pharmaceutical workshops, hospital operating rooms, and electronic factories. It can effectively intercept dust, pollen, and some bacteria, ensuring the cleanliness and comfort of indoor environments.

  This medium efficiency non-woven fabric filter uses high-quality synthetic fibers or glass fibers as filter materials, which have the characteristics of large dust holding capacity, low resistance, and uniform wind speed. Common specifications include multiple efficiency levels such as F5, F6, F7, F8, F9, etc. The frame material is mostly galvanized steel plate, aluminum alloy or stainless steel, and the structural form is mainly bag type, but there are also plate and folding types. The product complies with the national standard GB/T 14295-2019 "Air Filters" and has undergone strict initial and final resistance tests to ensure stable operation at rated air volume, stable and reliable filtration efficiency, and to meet the purification needs under different working conditions.

  When selecting, it is necessary to match according to the actual air volume, installation space size, and required filtration efficiency level. If the environmental dust concentration is high, it is recommended to choose a bag type medium efficiency filter with a larger dust holding capacity; If space is limited, compact panel or folding structures can be considered. Please note that medium efficiency filters are not suitable for removing gaseous pollutants or ultrafine particles (such as PM0.3 or below). Such requirements require the use of activated carbon filters or high-efficiency HEPA filters. When purchasing, it is necessary to confirm whether the interface size is compatible with the existing air duct system, in order to avoid installation difficulties or air leakage caused by size discrepancies.

  During installation, it should be ensured that the airflow direction is consistent with the arrow marked on the filter. A sealing gasket should be installed between the frame and the box to prevent bypass leakage. In daily maintenance, it is recommended to regularly monitor the pressure difference before and after the filter. When the pressure difference reaches twice the initial resistance or the specified final resistance value, it should be replaced in a timely manner. The general service life is 3-6 months, depending on the on-site air quality. Cannot be washed and reused. After disposal, it should be treated as industrial solid waste. Regularly inspect the framework for any deformation or damage to ensure the overall sealing and operational efficiency of the filtration system, and maintain good indoor air quality.
