The hydraulic system is the "blood circulation system" of construction machinery, and its cleanliness directly determines the stability and service life of the equipment. The P165569 Donaldson hydraulic filter, as a high-performance filtration product manufactured in accordance with the original factory standards of Donaldson, is specifically designed to provide comprehensive protection for hydraulic systems under various harsh working conditions, ensuring that the equipment is always in the best working condition.
Core value of the product
Leading filtration technology
It adopts gradient density glass fiber filter material and stainless steel central tube structure to form a three-dimensional filtration network, with a capture efficiency as high as 99.5% (based on ISO 16889 standard), which can effectively remove particulate contaminants, moisture and oxidation products in the oil.
Enhanced structural design
The steel plate shell of the stamping process is protected by both phosphating treatment and epoxy coating, enhancing its corrosion resistance by three times. The interior adopts high-strength sealing gaskets to ensure no leakage risk under a working pressure of 4MPa.
Wide adaptability performance
It is suitable for mainstream construction machinery brands such as Caterpillar, Komatsu and Volvo, and is particularly compatible with the hydraulic circuit systems of excavators, loaders, rollers and other equipment, fully complying with the original factory technical specifications.
Intelligent service support
It is equipped with a built-in bypass valve and a magnetic clogging indicator. When the filter element reaches saturation, it will automatically prompt for replacement, avoiding system failures caused by neglected maintenance.
