Description
When you’re running equipment in dusty conditions all day, your engine’s inner air filter is the last line of defense against fine particles that can slip past the outer filter. A worn air filter lets dirt and debris straight into your engine’s cylinders, where it acts like sandpaper on pistons and rings. This Baldwin inner air filter element works with your existing outer filter to give your engine the cleanest possible air, keeping it running strong through long work days.
What You’re Getting
- Compact design at 11 7/16 inches long with 2 13/32 inch outer diameter that fits perfectly inside your outer filter housing
- Multi-layer pleated media that captures particles while allowing the airflow your engine needs
- Works as part of a two-stage filtration system for maximum engine protection
- Direct replacement—no modifications needed
Built for Real Farm Work
This filter fits a wide range of heavy equipment from trusted names like Case, Caterpillar, John Deere, New Holland, Gehl, Vermeer, and Volvo. Whether you’re running a loader, excavator, tractor, or skid steer, this is the type of filter that came on your machine from the factory. It’s built to handle the dust and debris that comes with construction sites, farm fields, and job sites.
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. You’ll get reliable filtration that protects your engine investment.
Installation Notes
When swapping filters, take a minute to clean out the air box and check for any cracks in the housing or loose clamps. A little maintenance goes a long way toward keeping your engine breathing easy. This inner filter works with outer filter RS3954 for complete two-stage protection.
