Production Process & Internal Structure
A complete air filter consists of pleated filter paper, inner and outer protective mesh, upper & lower end caps and elastic sealing gaskets. Dual-stage primary & safety inner filter design is optional for heavily dusty mining environments.
- Uniform deep pleating maximizes effective filtration area, expands dust storage capacity and extends service cycle.
- Hot melt integral bonding tightly connects filter media and end caps without gaps to prevent unfiltered air bypass leakage.
- Double-layer metal support mesh strengthens the whole cartridge, resisting deformation caused by long-term vibration and strong airflow impact.
- Various standard mounting interfaces support direct replacement for most mainstream machinery brands without modification.
Filter Media Options & Applicable Working Conditions
- Standard Resin-Impregnated Wood Pulp Filter Paper
Cost-effective universal grade with balanced air permeability and dust interception. Suitable for highway trucks and stationary generators. - Waterproof & Oil-Resistant Composite Filter Paper
Double deep resin treatment, remains stable under humid, muddy and rainy conditions. Ideal for excavators, loaders and farm machinery. - Anti-Static Conductive Filter Media
Eliminates static sparks for explosion-proof applications such as grain harvesters and chemical workshops. - Polyester Spunbond Filter Material
High tensile strength, not easy to crack during pleating, widely adopted for large industrial air intake systems.

Core Competitive Advantages
✅ Efficient Dust Interception
Premium filter media traps fine sand and dust, minimizing engine abrasion and avoiding costly premature overhaul.
✅ Large Dust Holding Volume
Optimized pleat layout extends replacement intervals and cuts equipment downtime and maintenance expenses.
✅ Low Airflow Resistance
Smooth internal air passages guarantee sufficient air intake, maintain stable engine power output and lower fuel consumption.
✅ Excellent Anti-Vibration & Anti-Deformation Performance
Dual metal support skeleton adapts to bumpy long-time operation of construction and mining vehicles.
✅ Reliable Sealing Performance
Elastic rubber gaskets closely fit filter housings to eliminate bypass risks of unfiltered dust.
✅ Wide OEM Interchangeability
Customized according to OEM part numbers, direct plug-and-play replacement without structural adjustment.
