Products Description

Powder Sintered Filter . Hydraulic oil filters serve as the critical component within hydraulic systems, engineered to eliminate solid particulates, gummy substances, and diverse contaminants from the fluid. Functioning through specialized porous media-such as fiberglass, filter paper, or metal mesh-these filters intercept harmful agents including dust, metal shavings, and oxides. This process safeguards precision components like hydraulic pumps, control valves, and cylinders from ingress of debris, thereby preventing mechanical wear, valve sticking, and line blockages. Ultimately, this ensures the system maintains optimal cleanliness, operational efficiency, and a prolonged service life. Powder Sintered Filter.

Classification of Hydraulic Oil Filters
Hydraulic oil filters can be categorized based on multiple dimensions, including their installation location, filter media, and structural design. Different types of filters undertake distinct filtration tasks within the hydraulic system.
Classification by Installation Location and Function
This is the most common classification method. Based on the specific installation position within the hydraulic system, the function and performance requirements of the filters vary significantly.

FAQ

1. Can metal filter elements withstand high temperature and high pressure?
Yes. Depending on material, operating temperature can exceed 600°C, and pressure can reach dozens of MPa. They are suitable for steam sterilization and high-pressure systems.

2. What filtration accuracy can be achieved?
Typically 0.1–200μm, selectable. Precision is controlled by sintering process and pore size, covering coarse to fine filtration needs.

3. Do they shed particles and cause secondary contamination?
No. They are integrally sintered with no fiber or particle shedding, ensuring high cleanliness for purity-sensitive applications.

4. How are they cleaned and regenerated?
Backwashing, ultrasonic cleaning, or chemical dissolution can be used. Filtration performance can recover over 90% of initial level, with many reuse cycles.

5. How is corrosion resistance?
316L stainless steel resists most acids, alkalis, and solvents. For special media, Hastelloy or titanium is available. Material selection depends on the specific fluid.
