Description

When you’re running Caterpillar equipment in dusty conditions, your engine’s two-stage air filtration system is what keeps expensive repairs at bay. This inner element is the second line of defense, catching the fine particles that slip past the outer filter. It’s the safety net that protects your engine’s internals when you’re working in sandy soil, demolition sites, or during harvest when the air is thick with chaff and dust.

What You’re Getting

Precision-sized inner element at 15 7/32 inches long and 8 5/16 inches outer diameter for proper fit
High-efficiency filtration media that captures fine dust while maintaining good airflow
Baldwin quality construction built to handle the vibration and temperature swings of heavy equipment
Direct replacement for RS3514 and RS3514XP outer filter systems
Professional-grade sealing that prevents bypass and maintains filtration integrity

Built for Heavy-Duty Work

This inner filter element is designed specifically for Caterpillar heavy equipment that uses the dual-stage air filtration system. Whether you’re operating excavators, loaders, dozers, or other construction machinery, this filter provides that critical second stage of protection. These machines work in some of the harshest environments—construction sites, quarries, and farm operations where airborne debris can destroy an engine in short order.

Made to Last

Baldwin has been making quality filters for decades, and they understand what it takes to survive in tough conditions. The pleated media holds its shape even when loaded with contaminants, and the construction is built to handle the constant vibration and temperature changes that come with heavy equipment operation. This isn’t just a backup filter—it’s engineered protection for your investment.

Installation Notes

Always replace inner and outer elements together as a set—the inner filter may look clean but can still be loaded with fine particles that restrict airflow. While you’ve got the air cleaner apart, take a minute to inspect the housing for cracks and clean out any accumulated debris. Make sure all seals and clamps are tight, because any air leak bypasses your entire filtration system.
