The Entaron HD4 is a compact air cleaner for construction and utility vehicles which is a third smaller than similar products but provides the same power. Thanks to freely positionable, self-locking retainer clips, a 360-degree rotatable cover and freely configurable intake manifolds, it is flexible in use. A central graphic element is provided by the formally integrated, surrounding retaining mounts of the clips. Design details such as the orange-coloured clip handles contribute to operational safety.
