The BALDWIN FILTERS RS3549 is a radial air filter element designed to protect heavy-duty equipment engines from airborne dirt and other airborne contaminants. With a 2-inch outside diameter and an overall length of 12.313 inches, this element is built for precise fitment in demanding service environments. The end is molded using a urethane compound to form a reliable, consistent seal. Licensed HVAC and heavy-equipment technicians, as well as fleet service professionals, rely on this type of filter to maintain engine air quality and extend service intervals.
This air filter element is suited for use in heavy-duty and agricultural equipment applications. It serves as a direct replacement for several OEM and cross-reference part numbers, making it a practical sourcing option for service shops and fleet maintenance programs. Its radial shape allows for straightforward installation in compatible filter housings found on construction, agricultural, and industrial equipment platforms.

Installation should be performed by a qualified equipment technician. Power down the equipment and allow the engine to cool before servicing the air filter housing. Inspect the housing sealing surfaces for damage or debris before seating the new element. Ensure the urethane end cap seats fully and evenly against the housing to maintain a proper seal and prevent bypass.
