When you’re running Caterpillar equipment through dusty job sites or farm operations, this inner air filter element is your engine’s last line of defense against contamination. While the outer filter catches the big stuff, this inner element traps the fine particles that could slip through and turn your expensive engine into a paperweight. It’s the part of your two-stage air filtration system that keeps running clean when the work gets dirty.
What You’re Getting
- Precise fit at 12 3/8 inches long and 6 27/32 inches diameter for reliable sealing
- High-capacity filtration media that captures fine dust and debris that bypasses the outer filter
- Robust construction built to handle the vibration and airflow demands of heavy equipment
- Safety filter design that protects your engine when the outer element needs service
Built for Real Farm Work
This inner filter works with Caterpillar equipment that sees serious duty—whether you’re running excavators on construction sites, operating loaders around the farm, or running dozers through dusty conditions. These machines work in environments where clean air makes the difference between productive operation and costly engine repairs. The dual-stage system this filter is part of handles contamination loads that would overwhelm single-stage setups.
Made to Last
Baldwin has been making filters for heavy equipment since before hydraulics were common, and they understand what farm and construction work demands. Baldwin filters are built to handle the harsh realities of farm life—temperature swings, vibration, and constant exposure to dust that would overwhelm lesser filters. This inner element uses quality materials that maintain filtering efficiency throughout the service interval.
Installation Notes
This is the inner element in a two-stage air filtration system—always replace both outer and inner elements together during service. Always inspect your air cleaner housing for cracks or damaged seals while you’ve got the old filter out—any air leak here bypasses all your filtration. The attached gasket ensures proper sealing, and installation is straightforward with basic tools.
