This is perhaps the most precise press we have. Kraft (power) means that the cylinder is driven by an electric motor, and Luft (air) means that the printed sheet is returned automatically when the cylinder returns. A blade of air lifts it off the cylinder and lets it glide into the delivery tray. Very sophisticated. The picture below shows the air pump.

This press is the second one from the top on the About page, just below the Berlin Kraft, and above the other Nürnberg Hand Press.
