Product Details

The original Caterpillar 4L9851 air filter element is designed to provide maximum dust holding capacity and ultra efficient filtration in extreme working environments. As a replacement part certified by Cat, it uses multi-layer cellulose/polyester media and silicone free sealant, with high filtration efficiency. This component is designed specifically for mining, construction, and quarry applications, protecting the engine from abrasive particles and significantly reducing premature wear of the turbocharger and cylinder.

The 4L9851 air filter is strictly manufactured according to the original factory specifications, ensuring perfect compatibility and compatibility with numerous Caterpillar engines. For engine models such as C7, C9, C13, and C15 commonly found in heavy equipment such as excavators, bulldozers, and wheel loaders, it is an essential upgrade accessory. In addition, it is also very suitable for Caterpillar generators, providing reliable protection in power generation applications. The advanced design of 4L9851 maximizes airflow while maintaining strict filtration standards, allowing the engine to breathe freely and operate more efficiently. No matter if you are in industries with frequent dust and debris such as construction, mining, agriculture, or others, this air filter can keep your equipment running smoothly and minimize downtime.
Compared with similar after-sales products, the dust capacity has increased, and the radial sealing technology can prevent air bypass even under high pressure. It has good elasticity in extreme environments, and the hexagonal fold design maintains structural integrity during vibration, extending engine life and reducing fuel consumption through optimal airflow.
