DRLF series filter is used in return line, it can remove all the contaminants from the hydraulic system, keeping the oil back to the tank clean. 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 cleaned or changed in time, if the system cannot be stopped or nobody replaces element, the by-pass valve will open to protect the hydraulic system safety.
This series of filter is widely used in the hydraulic and system of heavy duty machine, mining machine, metallurgical machine and so on.
