High Dust Holding Replacement Engine Air Filter For Heavy Duty Truck

1. Production Craft & Internal Structure

Each air filter consists of pleated filter paper, inner & outer protective mesh, upper/lower plastic/metal end caps and elastic sealing rings. Dual-stage primary + safety inner filter design optional for heavy dust mining sites.

Deep uniform pleating technology maximizes effective filtration area, increases dust storage space and prolongs replacement cycle.
Hot melt integrated bonding tightly combines filter media and end caps without gaps, completely avoiding unfiltered air bypass leakage.
Double galvanized/stainless steel support mesh reinforces the whole cartridge, resisting deformation under long-term engine vibration and strong airflow impact.
Multiple standard interface sizes, direct plug-and-play replacement matching most mainstream machinery brands.

2. Classification of Filter Media & Applicable Scenarios

Standard Resin-Impregnated Wood Pulp Filter Paper

Cost-effective universal grade, balanced air permeability and dust interception performance, suitable for highway trucks, stationary generators and general workshop air intake.
Waterproof & Oil-Resistant Composite Filter Paper

Double-layer deep resin dipping, no softening under muddy, humid and rainy working conditions, ideal for excavators, loaders, agricultural tractors and construction machinery.
Anti-Static Conductive Filter Media

Mixed conductive fiber to eliminate static sparks, explosion-proof for grain harvesters, flour processing and chemical powder workshops.
Polyester Spunbond Filter Material

High tensile strength, not easy to break during pleating processing, for large industrial air intake dust removal systems.

3. Core Technical Specifications

Filtration efficiency: ≥99.5% for 3μm fine dust particles
Working temperature range: -30℃ ~ +85℃
Support mesh: Hot-dipped galvanized steel wire mesh / SUS304 stainless steel mesh
Sealing material: Oil-resistant EPDM rubber, anti-aging and leak-proof
Structure types: Single-stage air filter, primary + safety inner double filter assembly
Custom shapes: Round, oval, rectangular flat panel air filters

4. Core Competitive Advantages

✅ High-efficiency dust interception

Premium filter paper captures tiny sand and dust particles, greatly reducing engine wear and avoiding costly early overhaul.

✅ Large dust holding capacity

Expanded pleat area extends service interval, cutting equipment downtime and spare parts maintenance expenses.

✅ Low airflow resistance

Smooth air channel ensures sufficient air intake volume, maintains stable engine power output and lowers fuel consumption.

✅ Strong anti-vibration & anti-deformation performance

Dual metal support mesh adapts to bumpy long-term operation of engineering and mining vehicles.

✅ Perfect sealing performance

Elastic rubber gaskets fit tightly into air filter housings to eliminate dust bypass risks.

✅ Wide OEM interchangeability

Customized according to original equipment part numbers, no modification required for installation.

5. Wide Application Fields

Construction Machinery: Excavators, loaders, bulldozers, road rollers, mobile cranes
Transportation Vehicles: Heavy-duty trucks, buses, mining dump trucks, semi-trailer tractors
Agricultural Equipment: Large tractors, grain combine harvesters, pesticide sprayers
Power Generation Equipment: Diesel generators, industrial air compressors
Industrial Ventilation: Workshop air intake systems, blower primary filtration

6. Customization & Global Export Service

Custom filter paper type, overall dimension, single/dual filter structure, rubber seal hardness and brand LOGO printing based on OEM drawings or part numbers. Free samples and technical datasheets are provided for customer performance testing. Strict inspection of pleating uniformity, sealing tightness and air permeability before shipment, packed in export cartons and fumigated wooden pallets. Mixed container loading with hydraulic filter elements, dust removal cartridges and industrial filter paper to save ocean shipping cost.
