introduction
The RFA series direct return oil filter is a specialized device for precise filtration of oil returning to hydraulic systems. Mounted on top of the oil tank with its cylinder partially submerged, it filters out metal particles generated by component wear, rubber impurities from seals, and other contaminants in the hydraulic system through its filtering elements (such as filter cartridges), keeping the oil returning to the tank clean. This, in turn, protects the hydraulic system from contamination, enhancing its stability and reliability.
Product Features
- High-efficiency Filtration: The RFA series employs high-precision filter elements that effectively remove tiny particles and impurities from the oil, ensuring its cleanliness.
- Compact Structure: Directly mounted on the oil tank cover plate, this filter boasts a compact design that saves space and contributes to a more streamlined system layout.
- Easy Installation: Being mounted directly on the oil tank simplifies the system piping, reducing installation difficulty and cost.
- Convenient Maintenance: When the filter element becomes clogged with contaminants, simply unscrewing the filter cover allows for quick and easy replacement.
- Comprehensive Protection Mechanism: Equipped with a filter element contamination indicator and bypass valve, the indicator signals when the filter element is clogged or insufficient inlet pressure occurs due to low system fluid temperature, prompting filter replacement. The bypass valve automatically opens to protect the filter and hydraulic system from malfunction.
- Reduced Bubbles and Air Re-entry: A diffuser at the bottom of the return oil cylinder ensures a smooth flow of oil into the tank, minimizing bubble formation and disturbing settled contaminants, thus reducing air re-entry.
- High Filtration Accuracy: With its filtration accuracy specified in absolute terms, this filter offers high filtration efficiency, ensuring oil cleanliness at a superior level.
application area
The RFA series direct return oil filter finds widespread application in various hydraulic systems, particularly in industries with stringent oil cleanliness requirements, such as petroleum, chemicals, metallurgy, aviation, electronics, power generation, pharmaceuticals, and environmental protection. It effectively removes impurities and contaminants from the oil, safeguarding hydraulic system components from wear and damage, extending system lifespan, and enhancing its stability and reliability. Additionally, this filter is compatible with a wide range of working media, including general hydraulic oil, water-glycol, emulsions, and more.
Customized filters of different specifications and models are available upon user's request.
