This cab filter panel captures airborne particulates before they enter the tractor cabin's climate-control system. It sits in the filter housing located on the cab's intake plenum, trapping dust, pollen, and debris from the incoming airstream. A loaded filter restricts airflow, reducing ventilation efficiency and allowing contaminants to bypass the media. The filter's pleated construction provides a large surface area for particulate retention while maintaining acceptable pressure drop across the element. On replacement, ensure the gasket seats fully against the housing rim to prevent unfiltered air from entering the cabin.
