High-efficiency HEPA air purifier, filtering 99.97% of harmful substances

    Panel HEPA filters are used when low airflow requirements and a controlled air distribution is required. These can often be used in the ceilings of controlled environments (Cleanroom class ISO 8 or better), as well as specialist applications such as downflow booths.

How are HEPA filters made?

     Most modern HEPA filters consist of interlaced fiberglass (boron silicate microfibers) or
synthetic material (PP+PET) fibers.  Fiberglass fibers are commonly made up of things like silica, alumina, calcium oxide, boron oxide, magnesium oxide or sodium oxide.  Synthetic material fibers are made from polypropylene (PP) or polyester (PET).  The interlaced fiber material is formed into a flat sheet and in manufacturing is pleated to increase the overall surface area of the filter exposed to the air flow.

How does an HEPA filter clean air?

   HEPA filters rely on a combination of three mechanisms to trap particles. What’s important about HEPA filters is they’re incredibly effective at capturing almost every size of particle. They are captured in the following ways:

1. Direct Impaction: The first way is by impact, where larger particles (within one radius or larger of the filter fiber) being carried in the air flow around the filter fibers impact and path, collide with a fiber, and because they are too big to get through, they get stuck.

2. Interception: Air flow is nimble enough to reroute around fibers, but, thanks to inertia, particles continue on their path and stick to the sides of fibers. 

3. Diffusion: Small, ultrafine particles move more erratically than larger ones, so they’re more likely to hit and stick to fibers. For the really small particles (less than 0.3 microns) these particles this small have so little mass that they actually get bounced around like a pinball when they hit gas molecules (this process is called Brownian motion). So the particles move in random zigzag patterns and they hit the fibers and get stuck

Application scenarios of HEPA high-efficiency plate filters

    HEPA high-efficiency plate filters are widely used in various environments that require air purification, especially in places with extremely high air quality requirements. Common application scenarios include hospitals, laboratories, clean rooms, food processing plants, electronic manufacturing plants, etc.

Easy to install

    The HEPA high-efficiency plate filter is designed with the convenience of installation in mind, and the installation process is simple and fast. Its standardized size and frame design enable this filter to be compatible with the vast majority of air purification equipment, air conditioning systems and cleanroom equipment, so users do not need to worry about installation mismatches. Its lightweight structure and easy-to-operate installation method not only save installation time but also reduce labor costs. At the same time, maintenance and replacement have become more convenient, which can effectively improve the working efficiency of the equipment and reduce the difficulty of long-term maintenance.
