The invention relates to a device for generating a hollow plastic profile, in particular a plastic tube, having an air guidance system for interior cooling of the tube, wherein said device allows for a more simple design, improved process properties, and better tube quality. The device according to the invention comprises an extrusion die (100) having a melt channel (114) encompassing the extrusion axis, an extruder that feeds plastic melt to the extrusion die (100), and a suction device for suctioning air through the interior of the profile opposite the direction of extrusion, wherein the extruder feeds the extrusion die (100) centrally and the suction device comprises a central suction tube (140) disposed within the melt channel and partial flow suction channels (144) connected to the central suction tube (140) in the suctioning direction and leading out of the interior of the extrusion die (100). The invention further relates to a corresponding method.
