1.INTRODUTION The series filter can be installed on the top or at the side of the tank. There is check vavle inside the filter. During maintenance, filter element is withdrawn for washing, the check vavle will closeautomatically to stop oil flowing out from the tank.
A vacuum indicator in the filter will signal when the pressure drop across the element reaches 0.018Mpa showing that the filter should be cleanes. If no maintenance is done, as the pressure drop rises to 0.02Mpa, the by-pass vavle in this filter will open to allow oil flowing into pump directly.
