ZJNF HEPA Grade Industrial Air Filter Material For Cleanroom Factory 0.3um Particle

How to Select the Right Industrial Air Filter Material‌

Choosing the appropriate industrial air filter material requires a comprehensive consideration of filtration accuracy, temperature resistance, cost, and specific application scenarios. Below are the key factors and corresponding material selection recommendations:

‌Filtration Accuracy Requirements‌

• ‌Coarse Filtration (≥5μm)‌: Suitable for metal mesh filter elements (e.g., stainless steel wire mesh), which offer high strength and pressure resistance, commonly used in hydraulic oil pre-filtration.
• ‌Medium to High Precision (1-5μm)‌: Recommended to use fiberglass or synthetic fiber filter media, such as pleated filter cartridges, which provide high filtration efficiency at a moderate cost.
• ‌High Precision (≤0.3μm)‌: Requires ultra-fine fiberglass filter paper (HEPA grade), suitable for cleanroom environments in industries like pharmaceuticals and electronics.

‌Temperature Resistance Requirements‌

• ‌Ambient Temperature (≤60°C)‌: Polypropylene (PP) or chemical fiber filter cartridges can meet the requirements at a lower cost.
• ‌Medium to High Temperature (60-200°C)‌: Fiberglass filter media offer excellent high-temperature resistance, such as the fiberglass paper used in HEPA filters.
• ‌Extreme High Temperature (>200°C)‌: Metal powder sintered filter elements (e.g., stainless steel, titanium alloy) are necessary, withstanding temperatures above 600°C.

‌Cost and Durability‌

• ‌Low-Cost Scenarios‌: Paper or PP filter cartridges are suitable for budget-conscious and mild environments but require regular replacement.
• ‌Long-Term Durability Needs‌: Metal filter elements (e.g., sintered stainless steel) have a higher initial cost but a longer lifespan, making them ideal for high-dust or corrosive environments.

‌Special Environmental Adaptations‌

• ‌Corrosive Media‌: Prioritize materials like 316L stainless steel, titanium alloy, or PTFE (polytetrafluoroethylene).
• ‌High Humidity or Waterproof Requirements‌: Ensure the filter material has waterproof properties to avoid moisture affecting filtration efficiency.

‌Industry-Specific Examples‌

• ‌Power Plants/Mining‌: Require high-temperature, high-dust-holding-capacity fiberglass or metal filter elements.
• ‌Pharmaceuticals/Food‌: Demand high cleanliness, often using HEPA filters or synthetic fiber filter media.
