High Efficiency Air Filter Protect Engine from Dust Damage & Lower Long-Term Maintenance Cost

Production Craft & Structural Composition

A complete air filter assembly includes pleated filter media, inner & outer protective mesh, upper/lower end caps, rubber sealing gaskets and built-in safety filter (optional dual-stage design).

1. Deep Uniform Pleating Optimized deep pleating maximizes effective filtration area, enhances dust storage capacity and prolongs service interval.
2. Hot Melt Sealing Technology Hot melt adhesive tightly bonds filter media with end caps to prevent air bypass and unfiltered dust entering engine.
3. Double-Layer Reinforced Support Mesh Galvanized or stainless steel mesh prevents filter paper deformation under strong airflow and vibration.
4. Optional Primary & Safety Inner Filter Dual-stage design for severe dusty mining, desert and construction working environments.

Main Filter Media & Applicable Working Scenarios

1. Standard Resin-Impregnated Wood Pulp Filter Paper

Cost-effective, balanced permeability and dust retention. Application: Highway trucks, generators, light industrial machinery.

2. Waterproof & Oil-Resistant Composite Filter Paper

Double resin dipping, anti-softening under humid, muddy and rainy conditions. Application: Excavators, loaders, agricultural tractors, off-road engineering vehicles.

3. Anti-Static Conductive Filter Media

Conductive fiber blended to eliminate static sparks, explosion-proof. Application: Grain harvesters, flour processing equipment, chemical powder workshops.

4. Polyester Spunbond Filter Media

High tensile strength, suitable for heavy dust industrial air intake systems.

Core Standard Technical Parameters

• Filtration Efficiency: ≥99.5% for 3μm dust particles
• Operating Temperature: -30℃ ~ +85℃
• Support Mesh: Hot-dip galvanized steel wire mesh / SUS304 stainless steel mesh
• Seal Material: EPDM nitrile rubber, anti-aging and leak-proof
• Structure Type: Single stage air filter, primary + safety inner filter dual assembly
• Custom shapes: Round, oval, rectangular, flat panel filters

Core Competitive Advantages

✅ Superior Dust Interception Performance High-efficiency filter media blocks fine sand and dust, reduce cylinder wear, avoid early engine overhaul.

✅ Large Dust Holding Capacity Enlarged filtration area extends replacement cycle, cuts equipment downtime and maintenance costs.

✅ Low Airflow Resistance Smooth air passage ensures sufficient intake air volume, maintains engine power and reduces fuel consumption.

✅ Vibration & Deformation Resistance Dual metal support mesh adapts to long-term bumpy operation of construction machinery.

✅ Reliable Sealing Performance Elastic rubber gasket fits tightly into air filter housing, eliminates dust bypass risk.

✅ Wide OEM Interchangeability Customized according to original part numbers, direct plug-and-play replacement without modification.

Wide Application Scenarios

1. Construction Machinery: Excavators, loaders, bulldozers, road rollers, mobile cranes
2. Transportation Vehicles: Heavy-duty trucks, buses, dump trucks, semi-trailer tractors
3. Agricultural Equipment: Tractors, grain harvesters, sprayers
4. Power Equipment: Diesel generators, air compressors
5. Industrial Ventilation: Workshop air intake, industrial blower primary filtration
