Quick Details
Specifications
RLF filter series are used in return line, it can remove all the contaminants from the hydraulic system, and allow the clean oil flow back to the tank. The element of this series is made of glass fiber, it has high efficiency and filtration, large dirt capacity and lower initial pressure drop. There is a by-pass valve and a contamination indicator. The indicator will act when the pressure drop across filter element attains 0.35MPa,the element should be changed at this time. If the system can be not stopped or nobody replaces the element, the by-pass valve will open to protect the hydraulic system safety.
The series of filter is widely used in the hydraulic and lubrication system of heavy duty machine, mining machine, metallurgical machine and so on.
