Donaldson P532503 P532504 Air Filter Kit RadialSeal Primary Safety

The Donaldson P532503 and P532504 air filter kit comprises a primary radial seal element (P532503) and a safety radial seal element (P532504). Engineered with high-efficiency cellulose media, the kit delivers 99.9 percent filtration efficiency per ISO 5011 test standards. The RadialSeal technology ensures a reliable, leak-resistant seal without metal end caps, reducing weight and preventing corrosion. Pleatloc media spacing maintains uniform pleat geometry under vibration and pressure differential, maximizing dust holding capacity and service life. The primary element features an outer diameter of 281.6 mm, inner diameter of 147.9 mm, and length of 405.1 mm. This kit serves as direct replacement for Caterpillar OEM 6I2503 and 6I2504, Fleetguard AF25129M and AF25130M, and Baldwin RS3506 and RS3507.
