​Spot 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 areas (large halls, warehouses, shopping malls, assembly rooms etc.), particularly where the supply of air via ceiling diffusers is not possible or not practical. These diffusers / nozzles can be installed in the ceilings or side walls. The supply air direction can be changed by the swivel movement of the diffuser / nozzle within a range ± 40° in both the planes.
