The Baldwin RS3708 Radial Seal Outer Air Element is the outer filter stage in Baldwin’s radial-seal air filtration lineup, engineered to block contaminants before intake air reaches the engine and to seal firmly against the housing. It measures 17.25 inches in height, with a bottom inside diameter of 3.19 inches and a bottom outside diameter of 5.41 inches, and it weighs about 2.2 pounds; the element is not reusable. Designed for use with the RS3709 inner element, it is cross-referenced for Case equipment (Case 128781A1) and is sold as a dedicated Baldwin outer air element in its filter assembly.
