Classification and filtration grade classification of paper separator high efficiency filter

Paper partition high efficiency filter classification refers to the outer frame, paper partition high efficiency filter outer frame are galvanized frame paper partition high efficiency filter, wood frame paper partition high efficiency filter, aluminum frame paper partition high efficiency filter, stainless steel frame paper partition high efficiency filter.

Paper partition high efficiency filter filtration grade classification:

Paper partition subhigh efficiency filter, paper partition high efficiency filter.

Due to the characteristics of high efficiency, low resistance, and good wind speed uniformity, the paper partition high efficiency filter is suitable for high-grade purification equipment, filtration components at the end of the purification system, local purification equipment and clean.

Paper separator high efficiency filter application field: widely used in electronics factory, semiconductor, precision machinery, pharmaceutical, hospital food and other industries in civil or industrial clean workshop end filtration. Paper separator high efficiency filters are mainly used in aerospace, aerospace, electronics, semiconductors, wafers, biopharmaceuticals, hospitals, food industries and other occasions requiring high cleanliness. Paper partition high efficiency filters are used for the end filtration of air conditioning ventilation systems.

Paper partition high efficiency filter filtration common knowledge: high efficiency filter is for different grain, high efficiency filter efficiency up to 99.99 or more. Some people always put the efficiency level of the paper partition high efficiency filter and the level of the clean room corresponding, as if how many 9 ultra-high efficiency filters can be used to achieve 100 or even 10 levels of cleanliness. This is actually a false notion. The HEPA filter is the core of the system, but it is not the only condition to ensure cleanliness. The efficiency of the high efficiency filter to meet the requirements is only one of the necessary conditions, but also the most easy to achieve. In order to achieve the corresponding level of clean room, there should be many necessary conditions, such as wind speed, air exchange times, door and window sealing, and many aspects of clean room control for personnel.

The principle of high efficiency filter in the mechanical filtration of sewage treatment the most commonly used method, according to the filter medium is different, the working principle of high efficiency filter is mechanical filtration equipment is divided into particle medium filtration and fiber filtration two categories, high efficiency filter particle medium filtration mainly to sand and other particles as filter media, High efficiency filter through the adsorption of particle filter material and the porosity between the sand particles on the water solid suspended matter to achieve filtration, the advantage of high efficiency filter is easy to recoil, the disadvantage is that the filter speed is slow, high efficiency filter generally does not exceed 7m/h; The amount of pollution is small, and the core filter layer is only the filter surface; The filtration accuracy is low, only 20-40μm, which is not suitable for rapid filtration of sewage containing high turbidity.
