Performance and Characteristics

 

Core Advantages

 

 

 

High Filtration Precision: Uses glass fiber filter media with absolute filtration accuracy (1–30 μm) and efficiency ≥99%, meeting ISO standards.

Low Resistance & High Capacity: Low initial pressure loss (≤0.07 MPa), large oil-passing capacity, and high dirt-holding capacity for stable long-term operation.

Flexible Installation: Can be mounted directly on the oil tank cover or connected via piping, adapting to different system layouts.

Standardized & Customizable: Offers a range of standard models (60–1300 L/min flow rates) and supports custom specifications to meet specific hydraulic system requirements.

 

 

Function & Application

 

 

 

It is primarily used for:

Hydraulic System Return Oil Filtration: Captures wear debris (metal particles, rubber seal contaminants) from return oil to protect pumps, valves, and other components.

Oil Cleanliness Maintenance: Ensures oil returning to the tank remains clean, extending oil service life and reducing system downtime.
