Description

When you’re running big horsepower equipment through dusty fields or around feed lots, your engine’s breathing harder than a racehorse at the finish line. A clogged or worn-out air filter doesn’t just rob power—it lets in all that grit and debris that can turn your expensive engine into scrap metal in surprisingly short order. This Baldwin primary air filter is your engine’s first line of defense, catching the heavy dirt before it can clog your secondary filter or find its way into those precision-machined cylinders.

What You’re Getting

Large filter surface area with 12 13/32 inch diameter and 21 5/8 inch length for maximum dirt-holding capacity
Multi-layer filtration media that catches coarse particles while maintaining proper airflow to your engine
Robust end caps and gaskets engineered to seal tight and handle the vibration that comes with big equipment
Works as part of a two-stage system with the RS3721 inner element for complete engine protection

Built for Real Farm Work

This filter is designed for Case International and Steiger equipment that spends its days in demanding conditions. Whether you’re running a big articulated tractor through dusty cultivation work, pulling heavy tillage equipment, or operating around grain handling facilities, this filter handles the punishment that comes with serious farming operations where downtime isn’t an option.

Quality That Holds Up

Baldwin has been making filters for heavy equipment since before GPS guidance was even a dream, and they know what it takes to protect engines in harsh agricultural conditions. The pleated media maintains its filtering efficiency even when loaded with dirt, and the seals stay flexible through temperature swings and constant vibration.

Installation Notes

This is the outer element in your two-stage system, so you’ll want to replace both this filter and your inner element (RS3721) at the same service interval for best protection. Take a minute to clean out the air box housing while you’ve got it open—no sense putting clean filters in a dirty house. Check for any cracks in the intake piping or loose clamps that might let unfiltered air sneak past your expensive filtration system.
