Hydraulic filter elements are the core protective components of hydraulic systems. They effectively remove dust, rust, and wear particles, maintain fluid cleanliness, extend the service life of key components such as pumps and valves, and ensure long-term stable system operation.
Medium: General hydraulic oil, phosphate ester hydraulic oil, emulsion, water-glycol, fire-resistant fluid
Filtration Accuracy: 1μm – 100μm
Operating Pressure: 21 bar – 210 bar
Working Fluid: General hydraulic oil, phosphate ester hydraulic oil, emulsion, water-glycol
Operating Temperature: -30°C to +110°C
Sealing Materials: Fluororubber (FKM) seals, Nitrile rubber (NBR) seals
Filter media directly determines filtration precision, service life, and maintenance method. Please select the appropriate material based on your application requirements.
| Material | Filtration Precision | Dirt-Holding Capacity | Service Life | Cleanable | Recommended Applications |
|---|---|---|---|---|---|
| Wire Mesh | Coarse (>40μm) | Low | Long | ✅Cleanable | Suction filtration, coarse filtration |
| Cellulose Paper | Moderate | Medium | Short | ❌Not | Economical disposable filtration |
| Fiberglass | Fine (3~10μm) | High | Long | ❌Not | Recommended-High-pressure/ servo systems |
| Stainless Steel Fiber | Fine (3~10μm) | High | Long | ✅Cleanable | High-temperature/corrosive environments |
Different hydraulic systems have varying cleanliness requirements. Choose according to your system type.
| Grade | Precision | Typical Applications |
|---|---|---|
| Coarse | >40μm | Suction lines |
| Medium | 10~40μm | Return lines |
| Fine | 3~10μm | High-pressure / standard servo |
| Ultra-Fine | 1~3μm | Proportional / precision servo |
Our products are compatible with a wide range of hydraulic fluids and serve as direct OEM replacements with comparable performance. Wire mesh and stainless steel fiber elements can be cleaned with industrial fluid and reused. Cellulose and fiberglass elements require regular replacement based on operating conditions. Regular maintenance prevents valve sticking, pump wear, and system failures, ensuring optimal performance under heavy-duty conditions.
