Ningxia Yinchuan High Efficiency Filter Ningxia Yinchuan Ultra fine Fiberglass High Efficiency Filter Ningxia Yinchuan H13H14 Hundred level High Efficiency Filter

Description :

  Ultra fine glass fiber high-efficiency filter is a key component used at the end of air purification systems, mainly solving the problem of efficient interception of particles above 0.3 microns in the air. It is widely used in industries such as pharmaceuticals, electronics, and food that require extremely high levels of cleanliness. This high-efficiency filter uses ultra-fine glass fiber filter paper as the core filtration medium, which can stably achieve H13 or H14 level filtration efficiency, ensuring that the cleanliness of the air sent out meets international standards. In practical applications, high-efficiency filters are usually installed at the air supply end or laminar flow hood of clean rooms, which is the last line of defense to ensure a sterile and dust-free production environment. Their performance directly determines the final effect of the entire purification system.

  The core specifications of this high-efficiency filter are reflected in the filter material and structural process. The filter material adopts imported ultra-fine glass fiber paper, which has the characteristics of uniform porosity, low resistance, and large dust holding capacity. The outer frame is usually made of aluminum alloy, galvanized steel plate or stainless steel material, and is processed with precision folding and sealing technology to ensure that it does not deform or leak under high pressure difference. The partition board is often made of hot melt adhesive or aluminum foil to ensure uniform pleat spacing and effectively increase the filtering area. The execution standards usually refer to GB/T 13554-2020 "High Efficiency Air Filters" or EN 1822 standards. Before leaving the factory, each unit needs to undergo a scanning test to ensure there are no leakage points. The common test wind speed is 0.45m/s ± 20%, and the initial resistance is generally between 200-250Pa, depending on the size and air volume.

  When selecting ultrafine fiberglass high-efficiency filters, it is necessary to clarify the applicable scenarios and limiting conditions. It is suitable for the final filtration stage and is not suitable for directly processing high concentration dust or air that has not undergone initial or intermediate filtration, otherwise it will cause the filter element to quickly clog and shorten its service life. Compared with medium efficiency filters, high-efficiency filters have greater resistance and higher requirements for fan head pressure; Compared with ULPA ultra efficient filters, its filtration accuracy is slightly lower but it has a larger ventilation volume and better cost. When purchasing, it is necessary to confirm the size limitations of the installation space, the required air volume, and the cleanliness level requirements (such as hundred level, thousand level, ten thousand level). If the working conditions have high humidity, it is necessary to specify the use of moisture resistant filter materials or hydrophobic treatment to prevent damage to the filter paper.

  Installation and maintenance are key to ensuring the long-term stable operation of high-efficiency filters. During installation, handle with care and do not collide with the filter paper surface. Special sealing gaskets or liquid tanks should be used to seal the connection between the frame and the ceiling or air duct to prevent side leakage. In daily maintenance, the resistance changes of the filter should be monitored regularly. When the final resistance reaches twice the initial resistance or the specified value (such as 400-450Pa), it should be replaced in a timely manner. Do not attempt to clean or blow the ultrafine fiberglass filter paper, as this will damage the fiber structure and cause filtration failure. Common faults include rapid increase in resistance, leakage detection, etc. The former is often caused by failure of pre filtration, while the latter is often caused by poor installation sealing or transportation damage. Regular leak detection and maintenance records need to be established.
