Description
When you’re operating heavy equipment in dusty conditions—whether you’re grading roads with a motor grader, working construction sites, or running long hours in the field—your engine is constantly fighting against dirt, debris, and fine particles that can cause serious damage. A clogged or failing air filter lets contaminants straight into your engine, leading to premature wear and costly repairs. This Baldwin RS3508 air filter gives you the protection you need to keep running strong.
What You’re Getting
- Large filtration capacity with 13.5-inch length and 11.5-inch outer diameter for maximum dirt-holding ability
- High-efficiency pleated media that captures fine dust while maintaining proper airflow to your engine
- Robust construction with quality end caps and seals that won’t fail under pressure or temperature extremes
- Direct OEM replacement that installs without modifications—just like what came from the factory
- Compatible with inner filter RS3509 for complete two-stage filtration protection
Built for Heavy-Duty Work
This primary air filter is designed for Caterpillar construction equipment, Challenger agricultural tractors, and Wirtgen road construction machinery—machines that work in some of the toughest conditions you’ll find. Whether you’re running a motor grader on dusty job sites, operating an excavator in sandy soil, or working agricultural ground with a Challenger tractor, this filter handles the contamination load that comes with serious work.
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
This is a direct replacement—no modifications needed. 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. Remember to replace the inner filter RS3509 at the same time for complete system maintenance.
