Baldwin Filters RS3998 Air Filter Element Heavy-duty

Product Description

The BALDWIN FILTERS RS3998 is a heavy-duty radial air filter element designed to remove airborne dirt and contaminants from induction air entering large diesel and gasoline engines. With an outside diameter of 11.719 inches and an overall length of 23.313 inches, this element fits large-bore filter housings common in construction, agricultural, and industrial equipment. The molded urethane end seals the element securely in the housing, preventing unfiltered air bypass. Weighing 8.6 pounds, this is a robust, direct-service replacement intended for licensed technicians and fleet maintenance professionals performing scheduled air system service.

This filter element is suited for heavy-duty off-highway applications including construction machinery, agricultural equipment, and industrial power units that rely on large-format radial filter housings. It is a cost-effective service replacement that simplifies scheduled maintenance intervals. Cross-reference compatibility with Caterpillar 2453818, Donaldson P782106, Hastings AF2460, and Wix 549811 makes it a viable drop-in option when sourcing replacements across multiple equipment brands on a job site or in a fleet shop.

Installation Notes

Air filter element replacement is typically performed by diesel mechanics or heavy equipment technicians during scheduled service intervals. Shut down the engine and allow it to cool before opening the air filter housing. Inspect the housing canister and sealing surfaces for cracks or debris before seating the new element. Ensure the molded urethane end is fully seated and the housing cover is secured to prevent unfiltered air ingestion.
