AIR FILTER, SAFETY

The Donaldson P776019 is a safety air filter designed to protect your engine's clean air intake side. It serves as a secondary backup element inside the air cleaner housing, catching debris if the main outer primary filter becomes damaged or is accidentally misinstalled. Its primary job is to prevent dust and contaminants from entering the engine when the primary filter is being serviced. You should typically replace this safety filter every third primary filter change, or immediately if the primary filter failed and allowed dirt to pass through.
