The pure gas supply line (7) is surrounded by the fresh air supp ly line (8) at least along a longitudinal pipe segment and at least in said longitudinal pipe section the pure gas supply pipe (7) is constructed in suc h a way as to allow for the transmission of heat to fresh air flowing into the fresh air supply (8). The invention also relates to a paint dryer unit comprising several paint dryer modules which are positioned one after the other and configured as paint dryers according to the invention.
