Ultra-Fine Filtration Element: LCS4H2нН

The LCS4H2нН is a high-efficiency, heavy-duty filter cartridge engineered for precision fluid filtration in demanding industrial and mobile hydraulic or lubrication systems. Designed with an emphasis on fine particle retention and extended service life, it functions as a critical protective component in closed-loop and high-pressure fluid circuits. Its primary role is to capture and retain fine abrasive contaminants, wear debris, and other particulate matter from hydraulic oil, lubricating oil, or fuel, thereby ensuring fluid cleanliness, enhancing system reliability, and protecting sensitive downstream components such as pumps, valves, and actuators from premature wear and failure.

Filtration Rating ：

Nominal: 6 µm

Thread Connection ：

M20 x 1.5 or 1-1/16" UNF (Subject to OEM housing specification)

Product Introduction

Product Concept
The LCS4H2нН is a high-performance filtration element engineered for critical fluid purification in demanding industrial and mobile hydraulic systems. Designed to meet stringent cleanliness standards, it functions by capturing and retaining fine particulate contaminants, wear debris, and other impurities from hydraulic oil, lubricants, or fuel. Its construction ensures reliable protection of sensitive system components—such as pumps, valves, and actuators—by maintaining fluid integrity and extending equipment service life under high-pressure and high-cycle operating conditions.

Key Features & Advantages

High-Efficiency Filtration: Utilizes advanced multi-layer synthetic media with graded density to achieve consistent fine-particle retention and high dirt-holding capacity.
Robust Structural Integrity: Reinforced inner core and durable outer shell resist pressure surges, vibration, and media collapse, ensuring stable performance in dynamic environments.
Extended Service Life: Optimized media area and contaminant loading capacity reduce replacement frequency and lower total operating costs.
Leak-Free Reliability: Precision-molded gaskets and seals (e.g., NBR or FKM) provide secure sealing across a wide temperature and pressure range.
System Protection Features: May include an integrated bypass valve to maintain flow during cold starts or temporary overload, along with an anti-drain back function where applicable.
Direct OEM Replacement: Manufactured to exact original specifications for seamless compatibility, easy installation, and guaranteed performance in designated equipment.

Application Fields

Mobile Hydraulic Machinery: Excavators, loaders, cranes, agricultural tractors, and forestry equipment.
Industrial Hydraulic Systems: Machine tools, presses, injection molding machines, automation systems, and test rigs.
Power Generation Units: Lubrication and control oil filtration in turbines, diesel generators, and compressor stations.
Transportation & Heavy Vehicles: Hydraulic steering, braking, and lifting systems in trucks, buses, and specialized transport equipment.
Marine and Offshore Applications: Hydraulic winches, steering gears, and auxiliary equipment on vessels and offshore plat
