How often are sub-high efficiency filters replaced?
How often are sub-high efficiency filters replaced?Efficiency from sub-high efficiency filters h10-h12, using PP/glass fiber, used to capture 0.3~0.5 micron dust particles, H10 corresponds to an efficiency of 85%. Sub-high efficiency filters can be made into partitions, no partition, plastic frames, and other processes, with partition, for example, mainly using ultra-fine glass fiber paper as the filter material, offset paper, aluminum film, and other materials as a dividing plate, glued with a wooden frame and aluminum alloy, made of special silicone rubber, tasteless, the surface will not be hardened, and will not be very long. Cracks, chemical stability, and corrosion resistance can absorb the stress caused by thermal expansion and contraction without cracking, moderate hardness, and good elastic recovery. Each unit is tested by the sodium flame method, featuring high filtration efficiency, low resistance, and large dust capacity. Sub-high efficiency filter also has the characteristics of product diversification: relative to high-efficiency filters, sub-high efficiency filters have more choices, and sub-high efficiency filters have the advantages of low price, strong filtration, etc. Low-resistance sub-high efficiency filters use low-resistance and relatively inexpensive polypropylene fiber to replace glass fiber. Both fixed frame and separated frame, less material consumption, which makes it cheap and has good performance. How often are sub-high-efficiency filters replaced? Generally speaking, different types of sub-high efficiency filters have different use cycles, manufacturers have certain regulations on their requirements, purification recommendations according to the differential pressure indicator for replacement, and no instrument testing sub-high efficiency filters can be replaced once every six months. This can be a good way to determine the replacement cycle to extend the life of the equipment and reduce maintenance costs. |
