Jet nozzles are used for preference where the supply air from the diffuser has to travel a large distance to the occupied zone. This is the case in large rooms (halls, assembly rooms etc.), particularly when the distribution of air via ceiling diffusers is not possible or not practical. Here jet diffusers are arranged in the side wall areas.

 

The direction of the air stream from the jet nozzle can be easily adjusted manually to suit particular on site conditions
