Hepa Filter Making Machines

High Efficiency Particulate Air Filter HEPA is an abbreviation of "High Efficiency Particulate Air (Filter)". According to the definition of the U.S. Department of Energy, it is a foldable mechanical air filter that can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a particle size of 0.3 microns. The 0.3-micron diameter specification corresponds to the most difficult particles to filter, and it has a higher filtration efficiency for larger or smaller particles.

Filtration Grades: Common filtration grades include H11-H14, U15, U16 (EN1822), etc. In addition, there are ultra-HEPA high-efficiency filters, which can purify 99.9995% of particles; antibacterial non-partition high-efficiency air filters, which have antibacterial effects; and sub-HEPA high-efficiency filters, which are relatively cheap and were previously used in purification spaces with low requirements. Application Fields: HEPA filters are widely used in the air supply terminals of air conditioning systems in clean rooms in industries such as optoelectronics, LCD manufacturing, biomedicine, precision instruments, beverage and food, and PCB printing. They are also commonly used in air purifiers, vacuum cleaners, HVAC systems (heating, ventilation, and air conditioning systems), as well as high-cleanliness places such as operating rooms, animal laboratories, and aviation.

To make heap filter will need following machines:

2.a b two compounds filter gluing machine A specialized automated system designed for precise adhesive application in air filter manufacturing, particularly for end caps and HEPA filter sealing. Two-component adhesives consist of two separate parts that react chemically only when mixed. When mixed in a specific ratio (e.g., 1:1, 2:1, or 5:1, depending on the adhesive type), they undergo a chemical reaction to form a strong, rigid bond that resists heat, moisture, and mechanical stress—qualities essential for filter applications where bonds must withstand airflow pressure, temperature changes, or exposure to liquids. In summary, an A/B two-component filter gluing machine is a critical tool for producing high-quality, durable filters, leveraging the strength of chemical bonding to meet the rigorous demands of filtration applications.
