G1-G4 F5-F9 Bag Air Filters For Factory Industry

Function of Bag Air Filters‌

Bag air filters primarily capture airborne particles through physical interception and diffusion effects. The filter material is typically made of high-flow, low-resistance non-woven fabric, offering high dust-holding capacity. Key functions include:

1. ‌Solid-Liquid Separation & Liquid Purification‌ – Traps solid particles and suspended matter in liquids, improving purity, suitable for industries such as chemicals, food, and pharmaceuticals.
2. ‌Equipment Protection‌ – Prevents contaminants from damaging downstream equipment (e.g., compressors, engines), extending service life.
3. ‌Resource Recovery‌ – In petrochemical applications, valuable materials like catalysts can be recovered.
4. ‌Air Purification‌ – Removes industrial dust, microorganisms, and other pollutants, meeting air quality requirements in cleanrooms, hospitals, and similar environments.

‌Key Applications‌

1. ‌Industrial Sector‌

   • ‌Electronics Manufacturing‌ – Used in ultrapure water production for semiconductor fabrication, with filtration precision down to 0.5μm.
   • ‌Chemical & Metallurgical Industries‌ – Filters corrosive liquids and high-temperature gases, controlling dust emissions.
   • ‌Automotive Manufacturing‌ – Purifies air in paint shops, removing welding dust.

2. ‌Medical & Pharmaceutical‌

   • Ensures sterile conditions in hospital operating rooms and pharmaceutical cleanrooms by capturing microbes and particulates.

3. ‌Food & Beverage‌

   • Filters impurities from juices, beer, and other beverages to ensure hygiene and safety.

4. ‌Commercial & Civil Use‌

   • Pre-filters in HVAC systems to reduce load on high-efficiency filters.
   • Ventilation purification in commercial buildings and laboratories.

5. ‌Environmental Protection‌

   • Removes suspended solids in wastewater treatment plants to meet discharge standards.

‌Technical Features & Classification‌

• ‌Efficiency Grades‌ – Ranges from G1-G4 (coarse), F5-F9 (medium), to F9 (sub-high efficiency), with F8 achieving ≥95% efficiency for 0.4μm particles.
• ‌Structural Advantages‌ – Low side-leakage, minimal pressure drop, replaceable filter bags, and cost-effective operation.
