5High-efficiency filter without partition

The partitionless HEPA filter is mainly used to filter air-suspended granules below 0.3μm, and is suitable for strict one-way flow and high-level non-one-way flow cleanroom projects. Compared with the high-efficiency filter with partition, under the same air volume, it has the advantages of small size, light weight, compact structure, reliable performance, easy installation, stable efficiency and uniform wind speed; The efficient design without separators can achieve the highest efficiency with the highest resistance, thereby reducing the operating cost, especially the design of the hot melt adhesive can ensure the same pleat spacing, ensure the passage of the first airflow, and at the same time achieve high dust holding capacity and extend the service life.

7HEPA filter series

HEPA filter series is now the main filter used in most air purifiers and fresh fans, mainly used to filter small molecule particles with a diameter of less than 0.3μm dust and various suspended solids, HEPA filters are subdivided according to the current European grade G1-G4, F5-F - H10-H14 and U15-U17, the most common in air purifiers is H grade, of which H13 HEPA filter can achieve a total efficiency of 99.95%, The H14 HEPA filter can just reach 99.995%, and the purification level of the HEPA filter in the European standard is U, of which the total purification efficiency of the U17 HEPA filter even reaches 99.999997%, but because the production cost of the U-level HEPA filter is high and the production environment is very demanding, there are not many wells in the market. In addition to the grade, HEPA filters are also available in different materials. Among them, there are five types of common materials: chemical fiber PP filter material, composite PET filter material, meltblown filter material, polyester non-woven fabric and meltblown composite filter material, glass fiber filter material; The five types of HEPA filters of different materials have their own advantages and disadvantages, and the main application fields are also different, among which the HEPA filter made of compound filter material is widely used in air purifiers because of its acid and alkali resistance, corrosion resistance, high melting point, stable performance, non-toxic, tasteless, uniform distribution, low resistance, high efficiency, high strength, environmental protection, etc.

Product features

1. Effectively filter PM2.5, pollen, hair and other solids, with a removal rate of 99.99%

2. It can effectively remove formaldehyde, toluene, odor, TVOC and other gaseous pollutants in the air

Constituent materials

1. Frame material: paper frame, ABS plastic, aluminum alloy, stainless steel

2. Seal: polyurethane AB glue, hot melt adhesive

3. Separator: hot melt adhesive

4. Sealing strip: foam

5. Filter material: glass fiber filter material, chemical fiber PP filter material, imported or domestic composite filter material

6. Temperature, humidity: 80C, 80%

There is no specific definition of the size of the HEPA filter for the time being, and it is generally determined according to the specifications set by the manufacturer of the air purifier and fresh air fan.
