The flow has a longer reach and a narrower cone of flow, it is not as wide or diffuse as the Vortechs. I have not owned a Vortech so I cannot comment on the noise but the feedback on both gives me the impression that in both cases, some are noisy, some are not and a lot has to do with the thickness of material they are installed on and that they are installed properly. I would probably try to get some feedback from end users.
