Caterpillar 222-9021 Secondary Engine Air Filter

Description

The Caterpillar 222-9021 is a Secondary Engine Air Filter designed to work in tandem with a primary filter. Its role is to act as a final safety barrier, capturing any fine particles that may bypass the primary filter. This added layer of protection is vital for sensitive modern engines, preventing even the smallest contaminants from causing wear on precision components like piston rings and cylinders. The filter is constructed with high-quality media and a durable frame to maintain its integrity under extreme operating conditions.
