Production Craft & Structural Composition
The complete air filter assembly consists of 4 core parts: pleated industrial filter paper, inner & outer galvanized protective mesh, metal/PU filter end caps, and EPDM elastic sealing gaskets.
- Deep uniform pleating maximizes effective filtration area to store more dust, slow down pressure rise and extend service cycle.
- Hot melt integral bonding eliminates gaps between filter media and end caps, completely block unfiltered air bypass leakage.
- Dual-layer internal and external steel support mesh resists long-term engine vibration and airflow impact, preventing filter paper collapse under high dust load.
- Dual-core (main filter + safety inner filter) design optional for ultra-dusty mining, quarry and desert working environments to provide secondary double protection.
Main Filter Media & Matching Working Conditions

Core Competitive Advantages
✅ Ultra-High Filtration Precision
Uniform gradient fiber structure fully traps sand, dust and suspended particles, avoid engine cylinder scratch and early overhaul, greatly extend engine service life.
✅ Large Dust Holding Capacity
Optimized deep pleated design prolong replacement cycle, cut spare parts purchasing and machine downtime costs for fleet owners.
✅ Low Airflow Resistance
Smooth internal air channels guarantee sufficient air intake volume, maintain engine power output and improve fuel combustion efficiency to save fuel consumption.
✅ Waterproof & Moisture Resistant
Resin-impregnated filter paper will not absorb water and soften in rainy, muddy construction sites, avoid premature filter clogging and engine power drop.
✅ Reinforced Anti-Vibration Structure
Dual-layer metal support mesh resists continuous engine vibration, no filter paper cracking or deformation during long-distance transport and heavy-load operation.
✅ Perfect Sealing & Plug-and-Play Installation
Elastic rubber gasket tightly fits air filter housing; unified OEM dimensional tolerance for direct replacement without modification, save maintenance time. Wide Application Scenarios
- Construction Machinery: Excavators, wheel loaders, bulldozers, road rollers, tunnel boring equipment
- Transportation Vehicles: Heavy-duty semi-trucks, buses, dump trucks, off-road mining vehicles
- Power Generation Equipment: Diesel/gasoline generators, stationary air compressors
- Agricultural Machinery: Tractors, grain harvesters, agricultural irrigation supporting equipment
- Industrial Ventilation: Workshop fresh air intake primary filtration, industrial air compressor intake protection
