China High Efficiency Particulate Air Filter Manufacturer, Supplier, Factory

High-efficiency filters are essential industrial purification devices that effectively capture particles ranging from 0.1 to 0.5 microns, enhancing environmental safety. Their filtration principles include interception, inertia, electrostatic attraction, and diffusion, ensuring extremely high efficiency. Common high-efficiency filters use aluminum alloy frames and ultra-fine glass fiber paper as filtering materials, offering corrosion and heat resistance. HEPA filters are widely used in industries such as pharmaceuticals, food processing, and electronics, with a maximum filtration efficiency of 99.999%, playing a critical role in environmental protection and production safety.

PES cartridges are made from Polyethersulfone, ensuring consistent pore distribution that provides optimal bacteria retention. The polyester support on both the upstream and downstream sides ensures the filter’s resilience to pressure shocks. With its hydrophilic nature, the Polyethersulfone membrane allows for easy integrity testing, making it ideal for routine monitoring. It is chemically compatible with a wide range of substances and is free from surfactants, making it suitable for the most demanding filtration applications. These cartridges are widely used for sterile filtration in the production of Active Pharmaceutical Ingredients.

Polypropylene (PP) Cartridge Filters are widely used in water treatment, air purification, and chemical filtration. Made from thermally welded polypropylene, they effectively remove particles in liquids, such as in pharmaceuticals and beverages, while extending the lifespan of sterilization filters. These filters use physical, fiber, and depth filtration mechanisms to capture larger and smaller impurities, with micron-level filtration precision (as fine as 0.1μm). PP's chemical inertness prevents contamination, making it suitable for varying pH levels. With advantages like high filtration efficiency, long lifespan, chemical resistance, low cost, and ease of maintenance, they are commonly used in water treatment, food and beverage industries, pharmaceuticals, and air filtration systems.

MERV (Minimum Efficiency Reporting Value) is a standard used to evaluate the efficiency of air filters, measuring their ability to capture particles in the air. The MERV scale ranges from 1 to 16, with higher numbers indicating higher efficiency. MERV 1-4 is suitable for residential and low-demand commercial environments, primarily capturing large particles like dust; MERV 5-8 is used in ordinary homes and offices, removing medium-sized particles like pollen; MERV 9-12 is appropriate for hospitals, laboratories, and other high-demand environments, capturing bacteria, mold, etc.; MERV 13-16 is for clean rooms and high-standard laboratories, removing almost all small particles, including viruses. When selecting the appropriate MERV rating, it's important to balance filtration efficiency and airflow to avoid overburdening the system.

The selection of air filters should be based on the performance requirements of the application, including primary, medium, and high-efficiency filters. The four key indicators for evaluating air filters are air filtration speed, filtration efficiency, filter resistance, and dust holding capacity. Choosing the appropriate filter requires considering these indicators to meet the needs of different scenarios. Proper configuration of filters can enhance filtration efficiency, extend equipment lifespan, and reduce operating costs.
