Eusable Etched Metal Air Filter for HVAC Systems En 799 Class G2

Precision Chemically Etched Metal Filter Plate
Crafted from medical-grade 316L stainless steel (thickness range: 0.03-1.0mm), this filter plate utilizes chemical etching technology to achieve microhole apertures with 0.05-2.0mm precision (tolerance: ±0.01mm), fully compliant with ISO 3310-1 standards for particle separation

Key Advantages of Chemical Etching:

1. Ultra-High Precision:

   • Minimum pore size of 0.03mm with **>99% uniformity**, ideal for applications like pharmaceutical powder sieving (e.g., 200-mesh drug granules) and semiconductor material filtration
      
   • No burrs or deformation: Chemical etching ensures smooth edges and maintains 0.02mm flatness, enhancing fluid dynamics and achieving 37% higher flow efficiency compared to stamped filters
      

2. Superior Structural Integrity:
   Stress-free processing: Unlike laser or mechanical methods, chemical etching eliminates thermal or mechanical stress, preserving material properties and ensuring 15kg load capacity under high-frequency operations

3. Customizable patterns: Supports hexagonal, radial, and multi-layer designs for specialized industrial needs

4. Exceptional Durability:

   • 300-hour salt spray resistance (ASTM B117) and 8H Mohs hardness, making it suitable for acidic/alkaline environments in chemical processing and mining
      
   • Reusable design: Resists clogging and withstands repeated sterilization cycles, reducing long-term operational costs
      

Applications:

• Food Industry: Juice clarification (80-200μm pores) and spice filtration under FDA hygiene standards
   
• Biopharmaceuticals: Sterile liquid filtration (0.22μm precision) and catalyst recovery
   
• Industrial: Oil purification (99.7% impurity retention) and mining slurry separation
   

Available in 100-600mm diameters with customizable hole configurations, backed by GMP and RoHS certifications for global compliance

Technical Validation:

• Material integrity: No alteration to magnetic or temper properties, critical for medical sensors and EMI shielding
   

This chemically etched filter plate combines nanoscale precision, industrial-grade durability, and multi-industry adaptability, offering a sustainable solution for high-performance filtration needs
