ABSTRACT:
A filter assembly for fluid filtration having a push-activated lock and release mechanism. The filter housing has a sump for enclosing the filter media, a filter head, and at least one standoff protruding outwards for use in securing the filter head to a filter manifold. The filter manifold supports the filter housing with a filter locator. A filter guide having a rotator actuating mechanism secures and holds the filter head in place when the filter head is axially inserted. The rotator actuating mechanism has tabs and slots that rotate upon a transverse axial force from the standoff and from tabs on an internal shutoff. The internal shutoff has an inlet extension and an outlet extension with apertures for fluid ingress and egress. The internal shutoff tabs slidably contact and align the rotator actuating mechanism to secure and remove the filter head.
