회사 소식 What is a heavy duty air filter?

Core Design & Materials

1. Robust construction: Thicker filter media (cellulose blends, synthetic nanofibers, or oil-bath designs), reinforced pleats, heavy-gauge housings, and leak-proof seals to resist vibration, heat, and pressure surges. Many use two-stage filtration (primary coarse+secondary fine) for dusty worksites.
2. High airflow & filtration efficiency: Optimized for large-displacement diesel engines (trucks, excavators, generators), handling massive air volumes while capturing >99% of particles down to 0.3–1 micron.
3. Extended service life: Larger surface area and higher dirt-holding capacity reduce replacement frequency even in mining, construction, or desert operations.

Common Types & Applications

• Dry-type (cellulose/synthetic): Most common for heavy trucks, agricultural tractors, and stationary industrial engines; disposable or washable/reusable (e.g., K&N diesel filters).
• Oil-bath/centrifugal: For extremely dusty environments (quarries, off-road); uses oil or centrifugal force to trap coarse dust before fine media.
• Applications: Semi-trucks, bulldozers, loaders, marine vessels, power generators, and industrial compressors.
