LYC-B Series High-Precision Oil Purifiers: Core Equipment for Industrial Oil Purification & System Protection

Introduction  

Developed by LeFilter, the LYC-B Series High-Precision Oil Purifiers are engineered to address oil contamination issues in industrial hydraulic and lubrication systems. New oil often contains impurities and moisture during processing, storage, and transportation, failing to meet the cleanliness requirements of high-precision equipment. Equipped with a 3-stage filtration system (100μm coarse filter + secondary fine filter + tertiary fine filter) and a low-noise gear pump with strong self-priming capability (suction lift up to 1.5m), this series can quickly improve oil cleanliness to below ISO 4406 12/9. It also integrates multiple safety protections, including motor thermal overload protection and high-pressure overflow protection, making it suitable for bypass filtration in hydraulic systems, new oil pretreatment, and in-service oil purification in industries like steel, automotive manufacturing, and machinery processing.

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).
