These frameless diffusers are very convenient and quick to install. The ducts can be connected from either side and airflow is controlled using balancing dampers. Diffuser segments (except Lineo 500/600 models) can be connected into long lines or shapes using 90 degree corner pieces and lengths (dummy pieces are available for when only some segments have a technical requirement to be ducted). SINGLE models are attached to concrete ceilings, while PROFILE and PUZZLE models are attached to plasterboard ceiling profiles.
