Line profiles from the spatially resolved narrow-line region of NGC 4151 are separated into several bulk-motion components which show velocity dispersions two to three times larger than starburst nuclei with similar luminosity. The components are suggested to arise within the galactic disk and by filaments entrained in or situated along the shells of two super-bubbles. The large cone-like SW bubble is able to account for the SW soft-X ray excess and the hole in the NLR disk through which a UV-radiation cone emerges. The bubbles appear to be related to the nuclear radio source.
