Donaldson P782937 Safety RadialSeal Air Filter Assembly

The Donaldson P782937 is a safety RadialSeal™ air filter cartridge engineered as a secondary inner filter for heavy-duty diesel engine intake systems. It functions as a critical backup to the primary filter, preventing contaminant ingress during primary filter servicing and ensuring continuous engine protection. The radial seal design provides a secure, leak-resistant fit without metal end caps, utilizing high-efficiency cellulose media for proven dust-holding capacity across severe duty cycles. Constructed with non-metallic, self-supporting media, the filter element meets ISO 5011 efficiency test standards. Key dimensional parameters include an outer diameter of 155.5 mm (6.12 in), inner diameter of 137 mm (5.39 in), filter length of 416.5 mm (16.40 in), and overall length of 456.5 mm (17.97 in). The unit weighs approximately 3.01 kg and is manufactured in Germany.
