Introduction
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 fibre ; 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 lubrication system of heavy duty machine , mining machine , metallurgical machine and so on.
