Product Key Features
Progressive Density Structure: Features a graduated fiber density from the air-inlet to the clean-air side. This multi-layered depth filtration traps coarse dust on the outside and finer particles inside, maximizing dust-holding capacity (DHC).
Low Pressure Drop: Optimized for high-volume HVAC Air Intake Filter systems, maintaining a low initial resistance (≤ text Pa for G4). This ensures stable airflow and reduces energy consumption of AHUs.
Visual Installer Guide: Our premium Blue and White Filter Media uses the blue layer for air-inlet and white for air-outlet. This dual-color design guarantees that the Air Intake Filter is always installed in the correct direction.
Flame Retardant Safety: Synthetic fibers are treated with eco-friendly flame retardants. Fully compliant with DIN 53438-F1 and UL 900 Class 2 standards (self-extinguishing) for high-risk industrial facilities.
Material & Craftsmanship
100% Thermal-Bonded Polyester: Our Air Filter Media Roll is made of 100% premium synthetic PET fibers. Fibers are fused at precise temperatures without hazardous chemical adhesives, ensuring excellent mechanical durability.
Anti-Shedding Surface: Utilizes advanced surface thermo-stabilization technology to lock each filament in place. It completely eliminates fiber shedding even under high-velocity airflow, ensuring zero downstream contamination.
Washable & High Tensile: The robust synthetic web resists tearing, shrinking, and deformation. Material can be gently washed or blown out with compressed air for multiple reuses, lowering maintenance costs.
Flexible OEM Customization: As a trusted OEM Industrial Pre Filter Supplier, we control weights from 150g to 300g/m² and thicknesses from 10mm to 20mm. We offer custom roll slitting and precision die-cut pads to fit any intake grille.
Applications
Commercial Ventilation: Ideal as an Air Intake Filter in rooftop cooling units, central air conditioning, and building fresh air systems.
Industrial Spray Booths: Used as a high-performance pre-filtration blanket for automotive paint booths and surface coating lines to capture coarse overspray.
Power Machinery Protection: Shields air compressors, large industrial blowers, gas turbines, and diesel generator sets from internal mechanical wear.
Local Filter Manufacturing: Supplied as bulk raw rolls for global filtration workshops and distributors to die-cut into custom pre-filter pads or assemble into pleated metal-frame panels.
Competitive Comparison
| Technical Feature | Our Premium Filtration Media | Common Market Alternatives |
|---|---|---|
| Structure & Layering | Graduated Density Design | Single Density / Uniform Structure |
| Core Product Line | Our flagship Blue and White Filter Media offers excellent depth-loading capability | Standard uniform filter mats with very limited dust storage capacity |
| Airflow Performance | Optimized for HVAC Air Intake Filter systems, low initial resistance (≤ 30 Pa) | High resistance, reduces fan velocity and wastes operational energy |
| Fiber Integrity | Advanced thermal-bonded technology, zero fiber shedding under high airflow | Resin-bonded or loose filaments, prone to shedding and downstream clogging |
| Supply Form | Supplied as bulk Air Filter Media Roll with vacuum compressed export packing | Loose packaging, leading to high ocean freight costs and bulk volumes |
| Customization Support | Backed by an OEM Industrial Pre Filter Supplier supporting custom weights and sizes | Standard dimensions only, no customized slitting or custom engineering available |
