‌Industrial Air Filter Cartridge Materials and Their Differences‌

The materials used in industrial air filter cartridges vary significantly, with each type offering distinct characteristics in terms of filtration efficiency, durability, and suitability for specific applications. Below is a summary of the primary materials and their key distinctions:

1. ‌PP (Polypropylene) Filter Cartridge‌

• ‌Characteristics‌: Made from polypropylene microfibers through thermal bonding, featuring a three-dimensional microporous structure that can trap particles of various sizes. It offers good chemical stability, resistance to acids, alkalis, and organic solvents, and is cost-effective.
• ‌Limitations‌: Poor heat resistance, typically suitable only for ambient temperature environments.
• ‌Applications‌: Water purifiers, small air filters, and fuel filters.

2. ‌Wound Filter Cartridge‌

• ‌Characteristics‌: Constructed by precisely winding textile fibers (e.g., polypropylene or acrylic) around a porous core, with filtration accuracy adjusted by the tightness of the winding. Effectively removes suspended solids and particulate impurities from liquids.
• ‌Applications‌: Industrial liquid filtration, such as in petrochemicals and metallurgy.

3. ‌Activated Carbon Filter Cartridge‌

• ‌Types‌: Includes compressed types (sintered from coal or coconut shell activated carbon) and loose-packed types (activated carbon granules placed in a housing).
• ‌Characteristics‌: Adsorbs odors and organic gases but is not primarily designed for high filtration efficiency; often used in conjunction with pre-filters or medium-efficiency filters.
• ‌Applications‌: Air purification and chemical gas treatment.

4. ‌Metal Mesh Filter Cartridge‌

• ‌Characteristics‌: High strength, resistant to high temperatures and corrosion, and capable of withstanding high pressure and impact. Filtration accuracy is adjustable via mesh size, but cleaning and maintenance are more complex.
• ‌Applications‌: Pre-filtration or large-particle removal in industries like petrochemicals and metallurgy.

5. ‌Metal Powder Sintered Filter Cartridge‌

• ‌Characteristics‌: Offers high filtration precision for tiny particles, with excellent heat and corrosion resistance. However, it is costly and has higher fluid resistance.
• ‌Applications‌: High-precision fields such as aerospace, electronics, and pharmaceuticals.

6. ‌Fiberglass Filter Media‌

• ‌Characteristics‌: Resistant to high temperatures, highly efficient, and long-lasting, but relatively expensive.
• ‌Applications‌: High-efficiency filters (e.g., HEPA filters) for cleanrooms or the electronics industry.

7. ‌Synthetic Fiber Filter Media‌

• ‌Characteristics‌: A newer material that can replace non-woven fabrics and fiberglass, offering advantages like low resistance, high dust-holding capacity, and environmental friendliness.
• ‌Applications‌: Full range of filter products from coarse to high efficiency.
