Resin Impregnated Wood Pulp Filter Paper For Heavy-Duty Truck & Excavator Air Filter Cartridges

Main Product Categories & Application

1. Resin-Impregnated Wood Pulp Filter Paper

Made of imported wood pulp with phenolic resin dipping. High tensile strength, not easy to crack after pleating, cost-effective universal grade.

Application: Heavy trucks, excavators, generators ordinary engine air filters, general industrial dust filter cartridges.

2. Waterproof & Oil Repellent Composite Filter Paper

Double-layer deep resin coating, repel water mist and oil mist. No softening under humid, muddy and rainy working conditions.

Application: Construction machinery air filters, farm equipment intake filters, outdoor dust collectors.

3. Anti-Static Conductive Filter Paper

Blended conductive fiber to eliminate static electricity, prevent dust ignition and explosion risks.

Application: Flour mills, aluminum powder processing, chemical pigment workshop explosion-proof filter cartridges.

4. PTFE Membrane Laminated Polyester Filter Media

Surface filtration structure, dust hardly embeds into fiber. Easy pulse self-cleaning, high efficiency for micro fine powder.

Application: Powder coating booths, welding fume purification, pharmaceutical fine dust recovery.

5. PPS High Temperature Resistant Filter Media

Continuous operating temperature up to 200℃, resistant to acid flue gas and corrosion.

Application: Boiler flue gas filtration, asphalt mixing plant, metallurgical kiln dust removal.

6. Flame Retardant Filter Paper

Class B1 flame retardant performance, self-extinguishing without sustained combustion.

Application: Carbon black processing, metal grinding dust collection, coal dust filtration.

Core Competitive Advantages

✅ Uniform microporous fiber structure

Balances airflow and dust interception, maintains stable low resistance and reduces fan energy consumption.

✅ Large dust holding capacity

Optimized gradient fiber structure extends filter service cycle, lowering end-user replacement costs.

✅ Excellent pleating & hot melt adhesion

Good toughness for deep pleating; closely bonded with hot melt glue to avoid air bypass leakage.

✅ Multiple functional customized treatments

Waterproof, oil-proof, anti-static, flame retardant, PTFE lamination to adapt all harsh working environments.

✅ High wet tensile strength

Resist repeated pulse backblowing, less fiber shedding, long service life.

✅ Stable batch consistency

Strict laboratory testing for each batch; uniform thickness, air permeability and filtration precision.

Wide Application Scenarios
