6. DESCRIPTION OF OPERATION
Fluid flow paths
Fluid enters the filter through the inlet connection into the valve by the means of the
machine system pressure. The valve directs the flow to one of the reservoirs, according to
the user set position. First, the oil is pushed from outside to in through a filter element,
which collect the dirt particles. After that, the oil is pushed through a water separation
element, which separates water from the oil. The oil (red arrows) exits the filter through the
outlet connection. The water (blue arrows) trickles from the surface of the separation
element to the bottom of the filter bowl.
