LYC-C Box type mobile oil filter

The Box Type Mobile Oil Filter LYC-C Series represents a significant advancement in portable oil filtration technology. 

Unlike other LYC series oil filters, the LYC-C series features a robust metal shell enclosure that provides superior protection

 against external environmental contamination while achieving enhanced self-protection for the internal components.

 This fully enclosed design makes the LYC-C series particularly suitable for applications where the operating environment

 presents challenges such as dust, moisture, or physical impact risks.

The internal system of the LYC-C series incorporates the proven high-precision filtration system from the LYC-B series oil

 filter truck, delivering exceptional filtration accuracy and consistent performance. The combination of a protective outer 

shell with high-performance internal filtration creates a versatile, durable, and reliable oil purification solution for critical

 hydraulic systems.

The metal shell of the oil filter is engineered with a quick-opening structure that allows the cover to be rapidly removed 

without the need for any tools, enabling fast and convenient filter element replacement. This innovative design significantly 

reduces maintenance downtime and simplifies routine service procedures. A pressure gauge is conveniently installed on the

 panel to continuously indicate the operating condition of the system and the contamination level of the filter element, 

providing operators with real-time performance feedback.

A key distinguishing feature of the LYC-C series is the inclusion of a self-contained fuel tank. Oil stored in the integrated tank 

can be filtered to the required standard through self-circulation and then directly injected into the hydraulic system. 

This capability is particularly valuable for applications where external oil sources may be contaminated or where pre-filtration

 is essential before introducing new oil into the system. The self-contained tank functionality makes the LYC-C series especially

 suitable for hydraulic systems equipped with servo valves, proportional relief valves, and other precision components that 

demand high oil cleanliness levels.

Structural Characteristics

The LYC-C series is designed with a comprehensive set of structural features that ensure reliable performance, operational 

convenience, and extended service life:

1. Fully enclosed metal shell – The refined shell covers all components, providing robust protection against external 

contamination, physical damage, and environmental factors. This design ensures that the internal filtration system operates in 

a clean, controlled environment.

2. Ideal for high-requirement environments – The LYC-C series is particularly suitable for applications with stringent 

environmental requirements, including clean rooms, outdoor installations, and facilities where contamination control is critical.

3. High-performance gear pump – The unit is equipped with a specialized gear pump driven by an electric motor. The pump

 features low noise operation, strong self-priming capability, and smooth, stable performance, ensuring consistent oil flow and 

reliable filtration.

4. Overflow protection device – The high-pressure pipeline is equipped with an overflow protection device that effectively

 safeguards the hydraulic system from pressure surges and overpressure conditions, preventing component damage.

5. Thermal overload relay protection – The motor is protected by a thermal relay that prevents motor damage caused by 

overload conditions, extending the service life of the motor and ensuring operational reliability.

6. Coarse filter at suction port – A coarse filter installed at the suction port protects the oil pump from large particles and debris,

 significantly extending the service life of the main filter element and reducing maintenance frequency.

7. Two-stage fine filtration – The pump is equipped with two stages of fine filtration, ensuring that the oil rapidly achieves a high

 level of cleanliness. This two-stage approach provides superior contaminant removal and consistent outlet oil quality.

8. Customizable filtration precision – The fine filter elements can be selected with different precision ratings based on user 

requirements, allowing the unit to achieve the specific cleanliness level needed for different applications and system 

components.

9. Quick-opening filter housing – The oil filter housing features a quick-opening structure that enables the cover to be opened 

rapidly without any tools, simplifying filter element replacement and reducing maintenance downtime.

10. Panel-mounted pressure gauge – The pressure gauge on the panel continuously indicates the system operating condition 

and the contamination level of the filter element, providing operators with immediate visual feedback for proactive maintenance.
