1.Overview
Whether in high-temperature, high-pressure environments or continuous-operation scenarios, the LF series provides robust performance, serving as a trusted solution for enterprises seeking to optimize efficiency and reduce costs. Shengda LF series filters excel in delivering precision, reliability, and cost-efficiency, making them ideal for industrial applications.
2. Technical Features
High-Precision Filtration
Employing imported glass fiber media, LF series filters achieve a filtration efficiency of ≥99.5% with a beta ratio (β≥200), effectively removing particles ranging from 3μm to 200μm. This ensures compliance with ISO cleanliness standards. Their multi-layer filter elements balance coarse particle retention and fine particle adsorption, significantly extending the service life of hydraulic components.
Low Pressure Drop and High Dirt Holding Capacity
Optimized filter element designs minimize pressure drop, reducing replacement frequency and maintenance costs.
Material Compatibility and Corrosion Resistance
Available in glass fiber, metal fiber, and sintered stainless steel mesh, the filter elements suit various media, including hydraulic oils, lubricants, and emulsions. Seals made of fluororubber (FKM) or nitrile rubber (NBR) ensure resistance to oils and high temperatures, operating reliably from -30°C to 120°C.
3. Product Advantages
Versatility and Modular Design
The LF series supports multiple connection types (threaded, flanged) and pressure ratings (up to 100MPa), seamlessly integrating with hydraulic systems from diverse manufacturers. Modular filters enable quick replacement, featuring bypass valves to prevent system shutdown due to clogging.
Environmental and Economic Benefits
The high dirt holding capacity extends filter element life, reducing total cost of ownership compared to competitors.
4. Applications
LF series filters are widely used in applications demanding high fluid cleanliness:
Industrial Manufacturing: Hydraulic systems for metallurgical continuous casting machines, CNC machines, and paper mills, preventing valve sticking and servo motor wear.
Energy and Power: Gearboxes for wind turbines and lubrication systems for nuclear power plants, ensuring reliability under extreme conditions.
Construction Machinery: Hydraulic circuits for excavators and cranes, resisting dust and metal debris.
