21FC5121-110 × 250/20 is an efficient sealing oil filter designed specifically for the lubricating oil system of power plant steam turbines. Its excellent filtration performance and reliability make it an important component for ensuring the safe and stable operation of steam turbines. This filter element is widely used in power plants, ships, and other industrial equipment, mainly for filtering and purifying lubricating oil. It can effectively remove metal particles, impurities, and pollutants from the oil, ensuring the cleanliness of the lubricating oil, reducing equipment wear, and extending the service life of the equipment.

The 21FC5121-110 × 250/20 filter element adopts high-quality filtering materials, which have high filtration accuracy, corrosion resistance, and high temperature resistance, and can maintain stable filtration effect in complex working environments. Its design fully considers the special requirements of the power plant turbine lubricating oil system, which can operate stably for a long time under high pressure and high temperature conditions. In addition, the filter element also has a large dirt holding capacity and a low initial pressure difference, which can maintain efficient filtration capacity during long-term operation, reducing the maintenance frequency and operating costs of the system.

The filtration accuracy of the 21FC5121-110 × 250/20 filter element reaches 20 μ m, which can effectively intercept small particles in the oil and prevent them from entering the core components of the equipment, thereby reducing the risk of equipment failure. At the same time, the structural design of the filter element optimizes the flow path of the oil, reduces flow resistance, and improves the operating efficiency of the system. In addition, the filter element has undergone strict quality testing, including filtration accuracy testing, flow pressure difference testing, and pressure resistance performance verification, to ensure its excellent performance in practical applications.

The 21FC5121-110 × 250/20 filter element is mainly used in the lubricating oil system of power plant steam turbines. Its efficient filtration capacity can significantly improve the cleanliness of lubricating oil and ensure the safe and stable operation of steam turbines. In addition, the filter element also has good interchangeability and easy installation, which can quickly adapt to various devices and provide users with efficient and convenient maintenance solutions. In ships and other industrial equipment, this filter element also performs well and can meet the filtration needs under different working conditions.
