LYC-A Series Oil Filters: Cost-Effective Oil Purification for General Industrial Use

Introduction  

The LYC-A Series Oil Filters from LeFilter are ideal for general industrial oil treatment needs, such as new oil filtration, in-service oil purification, and bypass filtration of hydraulic systems. With a 2-stage filtration design (100μm coarse filter + 3-40μm secondary fine filter) and a motor-driven gear pump (noise ≤65dB), the series offers stable performance with a rated pressure of 0.6MPa and a recommended viscosity range of 10-160CSt. Models cover rated flows from 25L/min (LYC-25A) to 150L/min (LYC-150A), suitable for small to medium-sized hydraulic stations and machine tool systems. It is a cost-effective choice for users with general cleanliness requirements (ISO 4406 15/12 below).

Operation

1. The machine consists of a motor-driven gear pump, dedicating low noise, strong self-absorption capacity, and smooth running characteristics.

2. The high-pressure pipe with overflow protection devices, which can efectively protect the safety of the hydraulic system.

3. The use of thermal relay protection to prevent motor damage caused by motor overload.

4. Coarse filtration of suction port can protect the pump and extend the life of the main filter.

5. After the pump has two precision filters,so the oil can quickly reach high cleanliness.

6. First precision filter can filter out the larger particles of impurities, and secondary precision filter can filter out smaller particles or moisture.

7. The precision filter chosen by different users for different precision, can provide better protection for the system.

8. Precision oil filtration housing with quick open structure, which can quickly open the cover and replace the filter without any tools.

9. Pressure gauge equipped on the panel, can show the continuous indication of the degree of contamination of the system operating conditions and filter.

Q&A: Your Concerns, Answered

Q1: How do I choose the right filtration precision for my needs?
A1: Select based on system requirements. For general hydraulic systems, 10–20μm is sufficient; for high-precision equipment (e.g., servo valves), 3–5μm is recommended. The B series offers tertiary filtration for extreme cleanliness needs.

Q2: How often should the filters be replaced?
A2: Monitor the pressure gauge—when pressure loss exceeds 0.01 MPa, replace the filter. In typical industrial use, this occurs every 200–500 operating hours (varies by oil contamination level).

Q3: Can the LYC filter handle high-viscosity oils?
A3: Yes, it supports viscosities of 10–160 CSt, covering most industrial oils (hydraulic oil, lubricating oil, turbine oil, etc.). For oils above 160 CSt, contact us for customized configurations.

Q4: What’s the difference between A and B series?
A4: The A series has two filtration stages (coarse + secondary precision), while the B series adds a tertiary precision filter—ideal for applications requiring ultra-clean oil (e.g., aerospace, precision machinery).
