Description

When your Caterpillar equipment is working hard in dusty conditions, the last thing you need is contaminated air reaching your engine. This inner air filter element provides the critical second stage of filtration in two-stage air systems, catching the fine particles that get past your outer filter before they can damage expensive engine components. It’s the backup that keeps your engine breathing clean when the work gets dirty.

What You’re Getting

Generous 7 1/4-inch diameter and 13 3/16-inch length for maximum filtration area
Multi-layer pleated media designed to capture fine dust while maintaining proper airflow
Precision-fit construction that seals properly inside the outer filter housing
Baldwin quality filtration that handles the demands of heavy equipment operation
Direct replacement for your existing inner element with no modifications needed

Built for Real Work

This inner element works as part of a two-stage air filtration system on Caterpillar heavy equipment. Whether you’re running a loader moving dirt all day, an excavator digging in sandy soil, or other heavy machinery in dusty job sites, this filter provides that crucial final barrier against engine contamination. The compact design fits perfectly inside the larger outer filter to give your engine the clean air it needs to keep running strong.

Made to Last

Baldwin has been making filters for decades, and they know what it takes to survive in harsh conditions. The pleated media holds its shape even when loaded with dirt, and the seals stay flexible through temperature swings and vibration. The quality construction ensures reliable protection for your engine investment, even when working in the toughest environments.

Installation Notes

This inner filter installs inside your existing outer filter housing—always replace both inner and outer elements together for best results. When swapping filters, take a minute to clean out the air box and check for any cracks in the housing or loose clamps. During exceptionally dusty conditions, you might need to service your air filters more frequently than normal intervals to keep your engine running at peak performance.
