European Standard G1/G2/G3/G4 Air Pre Filter With 95% Weight-Based Detection Efficiency

• Foldable structure: Adopting a folding design, it significantly increases the effective filtration area of the filter material (compared to flat-type filters, the filtration area can typically be increased by 3-5 times). Under the same air volume, it can reduce the wind speed of the filter material, extend the service life, and simultaneously reduce system resistance.
• Preprocessing function: Primarily serves as the first-level filtration in the air purification system, protecting the subsequent medium-efficiency filters, high-efficiency filters, and air conditioning equipment, thereby extending their service life and reducing the maintenance costs of the system.
• Filtering efficiency: The filtering accuracy is generally 5 microns, and the efficiency level can reach European standards G1/G2/G3/G4. The weight-based detection efficiency can reach over 95%. The filtering efficiency for particles ≥ 5.0 μm is 40% - 60%.
• Main application: Widely used in pre-filtering for central air conditioning and centralized ventilation systems, pre-filtering for large air compressors, clean return air systems, and pre-filtering for local high-efficiency filtration devices.

• Frame: Aluminium alloy
• Optional frame thickness: Ranges from 21 to 96mm
• Filter material: High-quality polyester synthetic fiber
• Reinforcement: Hot-dip galvanized square steel wire mesh
• Connection corner: Sturdy, ABS plastic corner/aluminum alloy corner
