Product Key Features
- Certified Flame Resistance: Meets F-1 DIN53438 and UL900-Class2 standards for industrial fire safety.
- Extreme Heat Tolerance: Operates reliably at a Max Working Temp of 170°C, ideal for heated spray booths.
- High Dust Capacity: Capable of holding up to 470g/m² of paint mist, extending replacement intervals.
- Static Electricity Prevention: Friction between the glass fiber and compressed air produces static, enhancing particle adsorption.
Material & Craftsmanship
- Fiber Quality: Premium imported glass fiber with high chemical and thermal resistance.
- Density Profile: Gradual density structure (G2, G3, G4 grades) for deep-bed filtration.
- Strength: Reinforced high strength glass fiber that resists tearing during high-velocity exhaust.
Applications
- Dual-Purpose Spray-and-Bake Booths: Essential for exhaust filtration in booths that switch between room-temperature spraying and high-temperature baking ovens.
- Heavy Machinery Painting: Safe and robust filtration for large-scale industrial coating facilities processing construction and agricultural equipment.
- Aeronautical Coating Lines: Reliable performance in high-velocity exhaust environments for aircraft and aerospace component painting.
- Metal Fabrication & Coating: Effectively filters metallic paint mist in high-temperature environments typical of steel structure coating.
- Petrochemical Equipment Coating: Provides a fireproof filtration solution for coating projects in areas with high safety sensitivity.
- Industrial Foundry Refinishing: Captures heavy overspray in facilities where ambient temperatures are elevated due to nearby metalwork.
