Product introduction

The XNL-series return line filter is a new type filter. It is used in the return line of hydraulic system to remove all the contaminants and keep the oil cleaning when the oil return to the tank. This series filter has some features as follow:

(a) it can be installed on the top of the tank

(b) the check valve will not let the oil flow out of the tank during maintenance the contaminants inside the element can be taken out when changing the element

(c) there is a by-pass valve on the top of the element, when the pressure drop across the filter element attains 0.4Mpa, the valve will open to protect the hydraulic system safety.

(d) the permanent magnets inside the filter can filter the magnetic particles above 1 um dia. from the oil

If you close the XNL series filter, the indicator should be equipped. When the pressure drop across the element reaches 0.35Mpa, the element must be changed.
