G3 G4 Synthetic Fiber Air Intake Filter Roll | High-Efficiency Pre-Filter Media
Our G3 G4 Synthetic Fiber Air Intake Filter Roll is the ideal solution for large-scale ventilation needs. Engineered as a high-efficiency pre-filter media, it serves as the first line of defense in air handling units, significantly extending the service life of expensive downstream filters.
Product Key Features
- Superior Elasticity & Vacuum-Packing: Features excellent high resilience , allowing the rolls to be compressed for vacuum-packed shipping to reduce logistical costs and storage space.
- Broad Thermal Stability: Operates effectively at temperatures between 50-100°C, making it versatile enough for almost any air intake operating environment, including high-heat industrial processes.
- User-Centric Installation: Designed for convenient installation and removal, allowing maintenance teams to perform quick filter changes and reduce system downtime.
- Optimized System Airflow: Due to its low resistance properties, this media makes the circulation of air through medium and high-efficiency filters more circulated and efficient, reducing energy consumption.
Material & Craftsmanship
- High-Strength Synthetic Fibers: Manufactured using premium, high-strength synthetic fibers that provide excellent durability and structural integrity under high-velocity airflow.
- Progressive Density Structure: The media is processed with a progressive structure where fiber density increases towards the air-exit side, allowing for depth-loading of particles rather than surface clogging.
- High Dust Holding Capacity: This specialized multi-layer design ensures a high dust holding capacity, trapping significant amounts of contaminants to protect sensitive downstream equipment.
- Low Resistance Matrix: The fiber arrangement is optimized for low air resistance, ensuring maximum airflow efficiency and minimal pressure drop.
Applications
- Commercial HVAC Systems: Ideal as a primary efficiency pre-filter for office buildings, hospitals, and shopping centers to maintain indoor air quality.
- Industrial Air Handling Units (AHU): Serves as the first line of defense in industrial AHUs, shielding expensive downstream filters from coarse dust.
- Paint Spray Booths & Coating: Specifically used for ventilation intake filtration in painting rooms and coating workshops to ensure clean airflow for finishing lines.
- Cleanroom Pre-filtration: Critical for air purification workshops and cleanrooms to extend the life of HEPA and ULPA filtration systems.
- Manufacturing Base Material: Acts as the high-quality base material for producing primary efficiency filter bags and specialized industrial filter pads.

Frequently Asked Questions
Q1: How does the “progressive structure” improve my filtration performance?
Our progressive structure increases fiber density toward the clean-air side. This allows the media to trap larger particles at the front and smaller ones deeper inside, resulting in a much higher dust holding capacity compared to uniform filters.
Q2: Can this filter media be used in high-heat industrial environments?
Yes. It is designed to operate effectively at temperatures between 50-100°C, making it suitable for diverse and demanding industrial air intake environments.
Q3: Will vacuum-packing damage the filter’s shape or efficiency?
Not at all. The material has excellent high resilience (回弹力). It can be vacuum-packed for cost-effective shipping and will return to its original thickness and shape immediately upon unpacking.
Q4: How does this pre-filter help save energy?
By utilizing a low resistance design, our media allows air to flow more freely. This ensures that air circulation is more circulated through the entire system, reducing the load on your fans and lowering energy costs.
Q5: Is it compatible with different installation methods? A: Absolutely. It is designed for convenient installation and removal. Additionally, the material is versatile enough to be tailored, sewn, or even ultrasonic welded to fit specific requirements.
