    HEPA filters are mainly used to capture particulate dust and various suspended solids below 0.5um, as the end filter of various filtration systems. Ultra-fine glass fiber paper is used as filter material, rubber sheet paper, aluminum foil board, and other materials are folded as dividing plates, new-type polyurethane sealant is used for sealing, and the outer frame is made of galvanized sheet, stainless steel sheet, and aluminum alloy profile.

    HEPA filter material description:

    Air filter paper for H10-H14 level filters; can be used as a foldable roll material, small fold filter; temperature resistance up to 250 ℃. Product advantages: uniform fiber distribution, large dust holding capacity, low resistance, high strength, etc. , Is an ideal air filter material.

    Product introduction of HEPA filter material:

    Glass fiber filter paper (HEPA) for primary, middle, and high-efficiency air filters: Mainly used in cleanrooms or workbenches of 10,000 to 100,000, exhaust air from nuclear power plants, high-end household vacuum cleaners, air purifiers, gas masks, etc.

    Ultra-high efficiency air filter with glass fiber filter paper (ULPA): mainly used in chip factories and class 100, 10, 1 clean workshop, etc.

    The production process of high-efficiency filters and the key matters that should be paid attention to, ensure that the qualified rate of high-efficiency filters produced reaches more than 99% of our standard, and a series of corresponding inspection standards ensure that the qualified rate of our high-efficiency filters reaches 100 %.

    High-efficiency air filters can remove very small particles or suspended solids. It is widely used in many fields. When using high-efficiency air filters, people may have such a problem, that is, high-efficiency air filters. Is the higher the filtration efficiency, the better? Today we mainly analyze this problem.

    For this problem, we need to look at different situations. In production, some dust-free workshops with higher requirements need high-efficiency air filters to filter. At this time, the efficiency of the air filter is the higher the better. Okay, but we also need to consider other factors. The higher the efficiency of the air filter, the more energy it consumes. Therefore, the HEPA air filter only needs to meet certain requirements. There is no need to use a higher efficiency air filter. If it is used, the electrical energy will increase, and the requirements for air conditioning will also increase.

    For some clean rooms with tens of thousands or hundreds of thousands, HEPA air filters generally only need a certain level of HEPA air filters to meet the requirements, then there is no need to choose more efficient air filters, otherwise only It will increase energy consumption, increase costs, and cause unnecessary waste.

    When consumers choose HEPA air filters, do not think that the higher the efficiency of the HEPA air filter, the better. In fact, this idea is wrong. We need to choose the HEPA air filter according to our actual situation. The filter is just right, there is no need to pursue a more efficient air filter.

    High-efficiency filters are mainly widely used in the end filtration of civil or industrial clean places that require high cleanliness in the electronics, semiconductor, precision machinery, pharmaceutical, hospital, and food industries.
