Product Description
Engine Part 399-7921 Hydraulic Oil Filter for Heavy-Duty Construction Machinery
-
Core Functions
- Contaminant Filtration: Effectively remove metal particles, dust, sludge and other pollutants from hydraulic oil, preventing abrasive wear and jamming of precision hydraulic components such as pumps and valves.
- Hydraulic System Protection: Maintain the cleanliness of hydraulic oil, extend the service life of oil fluid, reduce the failure rate of the entire hydraulic system and ensure the stable operation of equipment.
- Perforce Maintenance: Preserve the fluidity and lubricity of hydraulic oil, keep the normal pressure and flow of the hydraulic system, and ensure the operating efficiency of construction machinery/vehicles.
Key Features
- High filtration efficiency: It can intercept tiny impurities in hydraulic oil with high precision, significantly reducing the abrasive wear of key hydraulic components.
- Robust structural design: The filter body has high pressure resistance and adaptability to harsh working conditions (such as high temperature, vibration); the sealing perforce is excellent, effectively preventing oil leakage and secondary pollution of the hydraulic system.
- Low flow resistance: The internal filter element structure is optimized to minimize the pressure loss of hydraulic oil during filtration, ensuring the normal flow of the hydraulic system.
- Long service life: Under standard working conditions, the recommended replacement cycle is 500-1000 working hours; the replacement cycle can be adjusted according to the actual harshness of the working environment.
