High-efficiency air filters are mainly divided into: high-efficiency filters with partitions, high-efficiency filters without partitions, high-V-BED high-efficiency filters, high-temperature high-efficiency filters, and liquid tank high-efficiency air filters
High efficiency filter without partition
The non-clapboard filter uses hot melt adhesive instead of aluminum foil with clapboard filter to separate the filter material. The absence of baffles enables a 50mm thick non-baffled filter to achieve the performance of a 150mm thick baffled filter. Under the condition of the same filtration area and filtration efficiency, the air volume of HEPA with 90mm thick outer frame can reach 1.3 times that of SPAN 150mm thick standard resistance type with partition plate and twice that of SPAN 150mm thick standard resistance type. It can meet the stringent requirements of today's air purification for all kinds of space and weight and energy consumption.
High efficiency filter with partition plate
The high-efficiency filter with partition board is made of superfine fiber as filter material, high-quality kraft paper hot rolling forming or offset paper and aluminum platinum as partition board, and is made of wood frame or aluminum alloy frame glue. It has the advantages of high filtration efficiency, low resistance and large air volume. High-efficiency filters with partitions mostly use coated paper with double-sided gluing as partitions, in order to prevent the partitions from shrinking under the influence of cold, hot, dry and wet, thereby emitting particles. Suitable for low-level non-unidirectional flow projects with various purification equipment and clean workshops. Among the partition filters, the aluminum partition filter is mainly used in high temperature or high humidity environment, and the paper partition filter is used in ordinary clean environment. The air volume with partitions is relatively large and can be used for high temperature filtration.
V-type close-pleated filter
It is used in general ventilation systems and has the characteristics of large filtering area, low resistance and long service life. It can be used as a pre-filter of the high-efficiency filter, thereby effectively extending the service life of the high-efficiency filter.
High temperature and high efficiency filter
The filter can be used in a high temperature environment of 250 ℃ ~ 400 ℃, and the filtration efficiency can reach 99.99 @ 0.3 μm.
Liquid tank type high efficiency filter
Liquid tank type high efficiency air filter, also known as liquid tank filter, is mainly used at the end of the clean room liquid tank sealed high efficiency air outlet, the filter level is H14-U15
