ABSTRACT:
The present invention provides an orientation device for enforcing correct orientation of a pleated filter element during installation into a filter support frame or filter housing, for example an automotive air cleaner. The orientation device includes at least one substantially rigid orientation rib positioned and mounted to have a portion of the rib extending between adjacent pleats of the pleated filter when the pleated filter is in an installed position. The orientation rib is positioned and mounted to block against at least a portion of the pleats of the filter element when the filter element is in an incorrect orientation, thereby preventing installation of the filter element.
