Abstract: A filter capture tool and filter removal tool useful to extract a filter from a compressor filter housing is disclosed. The filter capture tool and filter removal tool can be used separate an in some forms can be used independent of the other. In one form the filter capture tool can be inserted into a central open space of a filter element at which point a number of arms can be deployed from the capture tool to engage an interior surface and thereby capture the filter element. The filter removal tool includes an extension member that can be deployed from a base connected to a filter housing. The extension member can be connected to an arm which reaches from the base of the removal tool to the filter element to assist in removing the element from the interior of the filter housing.

Abstract: A ground electrode is provided having a ground electrode body, the ground electrode body having an anchored end and a non-anchored end opposite the anchored end. The ground electrode includes a plateau extending from a surface of the ground electrode body adjacent the non-anchored end. In illustrative embodiments, the plateau is formed by removing a portion of the ground electrode body near the non-anchored end. The plateau is configured to be exposed around its periphery. A noble metal tip is fixably attached to the plateau.
