PUZZLE Diffusers for Long Stretches

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 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). PUZZLE models are attached to plasterboard ceiling profiles.
