Product Overview

Or air filter cartridges are engineered for excavators, loaders, bulldozers, road rollers and other heavy-duty construction equipment, delivering reliable engine intake protection in extremely dusty, high-vibration and harsh outdoor environments. As a core component of the air intake system, it effectively traps airborne contaminants, reduces engine wear, and extends equipment service life.

Key Features

1. High-Efficiency Filtration MediaAdopts multi-layer composite fiber media (or imported HV filter paper) with scientific pore grading, achieving ≥99.99% filtration efficiency for 3–5μm particles. The high-density media captures fine dust, sand and silt, preventing abrasive wear to engine cylinders, pistons and bearings.

2. Exceptional Durability & Structural Strength

· Reinforced metal support mesh and spiral ribbing prevent media deformation under high airflow or vibration.

· Corrosion-resistant galvanized end caps and polyurethane sealing ends ensure airtightness and withstand -40°C to +120°C extreme temperatures.

· Closed-cell rubber seals eliminate air bypass, ensuring 100% filtered air intake.

1. High Dust-Holding Capacity & Low RestrictionOptimized pleating design maximizes filtration area, balancing low intake resistance and large dust storage capacity. It maintains stable airflow even in heavy dust, ensuring sufficient oxygen supply for combustion, improving fuel efficiency and engine power output.

2. Wide Compatibility & Easy Maintenance

· Fits mainstream models of Caterpillar, Komatsu, Volvo, XCMG, Sany and other construction machinery.

· Standard dimensions for direct replacement of OEM filters; tool-free installation and quick removal reduce maintenance time and cost.

· Long service intervals minimize downtime in mining, construction and tunnel operations.
