Engineered Pre-Filter Media Rolls For Superior Intake Air Protection
Progressive Density & High Dust Capacity
Deep-Bed Capture: The gradual fiber matrix of our intake filter media traps large particles on the surface and retains fine dust deep inside, preventing premature surface blinding while delivering reliable G1–G4 filtration efficiency.
Low Resistance: With an initial pressure drop of only 12–25 Pa, this high-efficiency pre-filter media significantly optimizes airflow, maintains consistent filtration performance, and reduces HVAC fan energy consumption.
Certified Flame Retardant (UL900 & DIN53438)
Dual Certification: Conforms strictly to UL900 Class 2 and European DIN53438 F1 safety standards, ensuring full compliance for intake air filtration systems across various efficiency classes.
Inherent Safety: Self-extinguishing fibers eliminate fire hazards in spark-prone paint curing rooms and automated industrial pre-filter media lines.
High-Velocity Structural Stability
Zero Fiber Shedding: Thermally bonded continuous fibers ensure that our pre-filter roll products withstand heavy airflow without tearing, migration, or drops in arrestance efficiency.
Downstream Protection: This high-performance intake filter layer effectively prevents particle carryover, protecting critical secondary filters and ensuring defect-free paint finishes.

Frequently Asked Questions About Intake Filter Media rolls
Q1: What is the main difference between G1, G2, G3, and G4 air intake filter media?
A: G1 through G4 represent progressive coarse dust filtration efficiency classes according to EN779 and ISO 16890 standards:
- G1 & G2 (100G–150G): Provide baseline pre-filtration with ultra-low initial resistance (12–15 Pa), ideal for high-velocity intake fan protection.
- G3 & G4 (200G–250G): Feature denser progressive fiber matrices delivering up to 91.20% filtration efficiency and higher dust holding capacity (up to 588 g/m²). They are widely used as primary intake media in spray booths and cleanroom pre-filtration.
Q2: Does Chuqi filter media pass international fire safety and flame retardancy audits?
A: Yes. All of our synthetic pre-filter media rolls and mats are certified to meeting UL900 Class 2 and European DIN53438 F1 flame retardant standards. This ensures full compliance during industrial facility safety audits and guarantees safe operation in spark-prone environments like automotive paint spray booths and baking ovens.
Q3: How does progressive density construction lower facility energy costs?
A: Standard single-density filter mats clog rapidly on the outer surface, causing pressure drop to spike and energy consumption to jump. Chuqi’s gradual density air intake filter media transitions from open, coarse fibers on the air-entry side to fine, dense fibers on the air-exit side. This structure captures large dust particles throughout the entire media depth, maintaining a low pressure drop (12–25 Pa) while saving fan motor power costs.
Q4: Can you provide custom pre-cut filter pads or custom roll dimensions for OEM orders?
A: Absolutely. As a direct-factory Air Filter Media Manufacturer, we offer high-speed automated slitting and die-cutting services. We supply standard bulk rolls (e.g., 2m x 20m) as well as custom-cut pre-filter panels, specific width rolls, and custom weight profiles (100GSM–250GSM) tailored to your exact AHU frame or ventilation housing specifications.
Q5: Will the fibers shed or break off under high airflow velocities?
A: No. Our media is manufactured using 100% continuous, high-tensile synthetic polyester fibers thermally bonded without chemical binders. This prevents fiber breakage or shedding even under heavy air streams up to 5400 m³/h, protecting sensitive machinery, secondary HEPA filters, and automotive paint surfaces from fiber contamination.
