Baldwin Filters PA3640 Automotive Air Filter

Product Description

The BALDWIN FILTERS PA3640 is a heavy-duty automotive air filter designed to remove airborne contaminants from intake air before it enters the engine. With an outside diameter of 7-15/16 inches and an overall length of 32-1/2 inches, this is a large-format filter suited to commercial vehicles, heavy equipment, or high-displacement engines that demand high-capacity air filtration. It weighs 8.25 pounds, reflecting the robust filter media and housing construction expected in demanding service environments. Licensed technicians and fleet maintenance professionals working on commercial and industrial powertrains install this filter as part of routine preventive maintenance.

The PA3640 is built for applications where standard passenger-car air filters are insufficient. Its larger dimensions make it a fit for heavy-duty trucks, agricultural equipment, construction machinery, or industrial engines where high air volume and extended service intervals are required. It is packaged individually and sold as a single unit. Technicians should verify the outside diameter and overall length against the application before ordering to confirm direct fitment.

Installation Notes

Air filter replacement is typically performed by a qualified diesel or heavy-equipment technician as part of a scheduled service interval. The engine should be shut down and cooled before servicing the air intake system. Inspect the air cleaner housing and sealing surfaces for cracks, debris, or damage before installing the new filter. Ensure the filter seats firmly and the housing is properly secured to prevent unfiltered air from bypassing the media.
