Why Choose Donaldson P780522?

Donaldson is a world leader in filtration technology for over 100 years, trusted by OEM manufacturers globally for agricultural, construction, and heavy-duty applications . The P780522 is engineered to meet or exceed original equipment specifications, delivering 99.9% ISO 5011-certified filtration efficiency using advanced cellulose media .

RadialSeal™ technology ensures a leak-proof, positive seal that prevents unfiltered air bypass – a common failure point with inferior filters . Pleatloc™ uniform pleat spacing prevents media bunching, maximising usable surface area and extending service life . Corrosion-resistant coated steel liners provide structural support under heavy engine load, maintaining optimal airflow throughout the service interval .

Designed as the primary outer element, this filter must be used in conjunction with the corresponding inner safety element P780523 for complete two-stage filtration protection .

Genuine Donaldson replacement components are designed to meet or exceed original equipment specifications. Trust the original.
