Description
When you’re running a compaction roller through dusty jobsites all day long, your engine needs every bit of protection it can get. Dynapac rollers work in some of the harshest conditions—from fresh dirt cuts to asphalt operations—and all that dust and debris can destroy expensive engine components faster than you’d think. This inner air filter element is your engine’s final line of defense, catching the fine particles that make it past the outer filter before they can cause real damage.
What You’re Getting
- Precise 9 3/32-inch length and 3 5/16-inch diameter for perfect fit in your Dynapac’s air system
- Baldwin quality construction designed to handle the constant vibration and temperature swings of compaction work
- Multi-layer filtration media that catches fine dust while maintaining proper airflow to your engine
- Direct OEM replacement that installs in minutes with no modifications needed
Built for Construction Work
This inner filter fits Dynapac CC122 and CC122C compaction rollers—machines built for serious earthwork, road construction, and site preparation. Whether you’re working on highway projects, parking lots, or subdivision development, these rollers put in long days compacting everything from base materials to asphalt. The dusty, demanding conditions require filtration that won’t quit when the work gets tough.
Made to Last
Baldwin has been making filters for decades, and they understand what construction equipment puts filters through. This inner element uses robust filtration media that holds its shape even when loaded with fine dust, and the seals stay flexible through the temperature swings and constant vibration that come with compaction work. It’s built to protect your investment in expensive engine components.
Installation Notes
This is part of a two-stage filtration system—always replace both the outer and inner elements together during service for maximum protection. While you’ve got the air cleaner housing open, take a minute to clean out any accumulated dust and check for cracks or loose clamps that could let unfiltered air bypass your expensive filtration entirely.
