Donaldson P628326 primary engine air filter, RadialSeal™ type. The pleated cellulose media holds 99.9 percent efficiency at ISO 5011 and carries a high dust-holding capacity, which is what keeps service intervals long on dusty site and haul-road machines. The leak-resistant radial seal seats into the air cleaner housing and stays put under vibration, and the galvanized steel liners support the pleats while keeping airflow open. Fits air cleaner assemblies sized for a 159 mm outer diameter, 124 mm inner diameter, 352 mm long element.

Key Features

99.9 percent filtration efficiency at ISO 5011 – fine dust stays out of the turbo and the cylinders
RadialSeal™ end face seals into the housing, so unfiltered air cannot sneak past the element under vibration
Galvanized steel outer and inner liners support the pleats and resist corrosion in humid storage and wet weather
Pleatloc™ spacing keeps the pleats even, which prevents media bunching and uses the whole surface area
Replace with Donaldson P629466 safety element for a complete air cleaner service

Signs of Wear

Replace the primary element when the restriction indicator shows blocked, or on the service interval – whichever comes first. Do not judge by looks alone: media that appears clean can still be loaded to the restriction limit. Never brush or blow out a cellulose element for reuse beyond its rated cleanings, and always seat the radial seal evenly by pressing the element straight into the housing until it stops.
