Helical Swirl Jet Diffuser

The helical diffuser puts angled vanes around the throat so the jet leaves spinning: throw distance of a nozzle, mixing of a swirl face. Air reaches the far side of a tall hall and equalises temperature on the way: the high-ceiling terminal that refuses to dump cold air on heads.
