Long throw nozzle WDA Model WDA-N-... WDA-F-... WDA-W-... WDA-D-... WDA-K-... WDA-R-... Description A horizontal supply air pattern is often required for large, high rooms such as theatres, concert halls, production halls, etc. Long throw nozzles type WDA are particularly suitable for this application. Their low noise level allows a high blow velocity, resulting in correspondingly long throw distances. The nozzles are also well suited to vertical throws. Please note, however, that nozzles which are designed for heating mode can cause draughts in cooling mode. This can be avoided if the...
