When you’re running a generator or industrial engine that you count on for power, clean air intake isn’t just important—it’s critical. Dust, debris, and contaminants that slip past a worn filter can destroy expensive engine components faster than you’d think. This Baldwin air filter catches all that harmful stuff before it reaches your engine, so you get reliable operation when the power needs to stay on.

What You’re Getting

  • Quality pleated filtration media that traps particles while maintaining proper airflow to your engine
  • Generous 10 3/4-inch length and 4 1/8-inch outer diameter for excellent dirt-holding capacity
  • Robust construction designed to handle vibration and temperature swings in generator applications
  • Direct replacement that fits like the original—no modifications or adapters needed

Built for Generator and Industrial Work

This filter is engineered specifically for Caterpillar generator sets and Lister-Petter industrial engines. These are the machines that keep the lights on during power outages, run equipment at remote job sites, and provide backup power when you absolutely can’t afford downtime. The filter handles the constant operation and demanding conditions these engines face.

Made to Last

Baldwin has been making filters for heavy-duty applications for decades, and they understand what continuous-duty engines demand. The filter media stays effective even after hours of operation, and the seals maintain their integrity through the heat cycles and vibration that come with generator work.

Good to Know

This is a straightforward replacement—remove the old filter and install the new one. While you’ve got the air cleaner apart, take a minute to clean out any debris in the housing and check that all clamps are secure. Keep a spare filter on hand if this generator provides critical backup power—you don’t want to be hunting for parts when you need the power most.
