Water Repellent Pleated Air Filter Cartridge Stable Air Intake For Agricultural Machinery Generator Set

Construction machinery, commercial trucks, generator sets, agricultural equipment and mining machinery frequently operate in harsh outdoor environments filled with sand, dust, pollen and industrial floating particles. Unfiltered air entering the engine will cause abrasive wear on cylinders, pistons and valve assemblies, resulting in power loss, higher fuel consumption, shortened engine service life and frequent overhaul downtime. To solve the common failures of poor dust holding capacity, early clogging and filter media damage of ordinary air filters, our factory launches full‑series heavy‑duty air filter elements, delivering high‑efficiency dust interception, stable air flow and long‑life air purification solutions for global heavy‑duty equipment operators, equipment maintenance suppliers and OEM manufacturers.

Main Product Types & Structural Features

We provide multiple configurations to cover light commercial vehicles, heavy trucks, off‑road machinery and stationary generator systems:

1. Primary & Secondary Outer‑Inner Air Filter Kit

Dual‑stage main plus safety inner filter combination. Outer filter captures most coarse dust; inner safety filter provides backup protection when outer element is replaced or damaged. Widely used for excavators, loaders, tractors, heavy‑duty trucks and large generators.

2. Round Cylindrical Air Filter Element

Classic cylindrical structure, easy installation and replacement. Available in single‑stage and dual‑stage versions, fits most truck, bus and stationary generator equipment.

3. Oval / Special Shaped Air Filter

Custom oval and irregular profile filters for special engineering machinery and original equipment replacement requirements.

4. High‑Flow Heavy‑Duty Pleated Air Filter

High‑density pleated design enlarges filtering area, improves dust holding capacity, suitable for mining sites and extremely dusty working conditions.

Filter Media & Reinforced Component Specifications

1. Filter Media ‑ High‑grade wood pulp air filter paper: Good stiffness, high dust holding, stable performance for general heavy‑duty equipment ‑ Composite polyester non‑woven media: Higher moisture resistance, suitable for humid and high‑humidity operating environments ‑ Water‑repellent treated filter paper: Resists moisture and mud splash, prevents paper softening in rainy‑wet sites
2. Structural Parts ‑ End caps: Galvanized steel / powder‑coated metal end caps, anti‑corrosion, tight bonding with filter media ‑ Inner support cage: Perforated galvanized metal inner core, prevents filter media collapse under strong negative pressure ‑ Sealing gasket: High‑elasticity EPDM rubber gasket, zero air leakage, avoids unfiltered air bypass entering engine

Core Competitive Advantages

First, reliable dust interception performance. Multi‑pleated filter media effectively traps sand and fine dust, reduces engine abrasive wear and lowers failure risk. Second, balanced air intake flow. Optimized pleat density ensures sufficient air supply, avoids insufficient power caused by filter blockage. Third, large dust‑holding capacity. Expanded effective filtering area extends service cycle, reduces filter replacement frequency and maintenance cost. Fourth, solid sealing & structural stability. Firm bonding between filter paper, end cap and rubber gasket, no air leakage; inner metal cage resists negative‑pressure deformation. Fifth, wide adaptability & OEM support. Match numerous OEM part numbers, support custom dimensions, logo printing and private labeling.

Wide Application Scenarios

Commercial transportation: Heavy‑duty trucks, buses, logistics vehicles Engineering machinery: Excavators, loaders, bulldozers, road rollers, mining machines Agricultural equipment: Tractors, harvesters, agricultural machinery Power equipment: Diesel generator sets, stationary power units Other off‑road equipment: Construction site machinery, forestry machinery

Customization & Global Export Service

We support custom outer diameter, height, pleat counts, filter media type and gasket form according to installation dimensions and OEM part numbers. OEM printing of customer part numbers and brand logos on end caps is available. Every batch undergoes strict testing for air permeability, dust holding capacity and sealing performance before shipment. Waterproof film wrapped and packed in export cartons plus fumigated wooden pallets. Mixed container loading with hydraulic filter elements, dust removal filter cartridges, filter end caps and industrial filter paper helps customers save ocean freight.

Our air filter elements are exported to Southeast Asia, Middle East, Europe, Australia, Africa and South America. We maintain long‑term cooperation with equipment spare‑part distributors, machinery repair shops and OEM manufacturers worldwide.
