High efficiency air filter manufacturers outer frame material selection and production requirements？

High efficiency air filter frame structure: high efficiency air filter frame mainly includes: paper frame, galvanized frame, aluminum alloy frame, stainless steel plate. There are plate type, and bag type structure.

High efficiency air filter filter material:

Fiber filter material mainly include: chemical fiber non-woven fabric, glass fiber filter material, some manufacturers have cotton fiber and chemical fiber mixed filter material, other metal mesh, etc.

High efficiency air filter production method: mostly folding molding, metal mesh and filter material composite folding.

Medium effect filter structure:

The frame materials are mainly galvanized steel plate, aluminum alloy profile, plastic frame, paper frame, etc.

Medium effect filter media mainly include:

Chemical fiber, glass fiber and PP materials. At present, the bag type filter with glass fiber and PP filter material is the most used. As the domestic production of coarse, medium pocket air filter bag manufacturers are numerous, the use of materials, structure is also a variety of.

At present, the mainstream manufacturers and foreign factories use glass fiber filter material and part of the chemical fiber filter material, chemical fiber by its low price and low resistance advantage to occupy more and more market.

High efficiency air filter structure:

The main use of the outer frame: aluminum alloy profile, multi-layer plate frame, aluminum plate frame, galvanized steel frame, the use of aluminum alloy profile frame, the main production of square shape structure. (high efficiency air filter manufacturer)

Filter media: the use of glass fiber, chemical fiber gradually in use, at present, some foreign manufacturers with electrostatic polytetrafluoroethylene fiber (electret) manufacturing high efficiency filter, commonly known as PTFE.

High efficiency air filter structure and partition and partition. No separator mainly adopts thermal sol as the separator of filter element, which is convenient for mechanized production. In addition, it has the advantages of small volume, light weight, easy installation, stable efficiency and uniform wind speed. At present, a large number of filters required by clean workshop are mostly non-partition structure. (high efficiency air filter manufacturer)

With a high efficiency partition, aluminum foil, paper folded as a filter element separator, the formation of air passage. Partition board is made of high quality kraft paper, hot rolling forming or offset paper for partition board.

At present, double-sided coated paper is used as partition board, the main purpose is to prevent the partition board from shrinking under the influence of cold, hot, dry and wet, so as to send out particles. However, according to our company’s experience over the years, when the temperature and humidity change, this kind of partition paper may have large particles, resulting in unqualified cleanliness test of clean workshop

(There have been several customer complaints about this.) Therefore, for places with high cleanliness requirements, customers should be recommended to use high efficiency air filters without partitions. The price of the baffle filter in foreign countries is higher than the price without baffle, so there are fewer places with baffle in foreign countries.

In addition, V-shaped channels without baffle filters further improve dust uniformity and extend service life compared to rectangular channels with baffle filters. The clapless filter for ventilation avoids the use of metal parts and is easy to dispose of, meeting the increasingly stringent environmental requirements.

Except for some special occasions where high temperature resistance and high safety requirements are required, no baffle filter can replace the baffle filter.
