Nozzle outlets, as in the case of slot diffuser outlets, can be regarded as a standard permeable outlet, fitted with optional amount of nozzle. The nozzle itself is a long extrusion, diameter of 18 mm opening. A special long extrusion was chosen as this geometry assures that the air will always leave at a perfect right angle to the textile air duct. Here the nozzle has small advantage over the inject outlets, where a high velocity inside the outlet can cause the air from the orifices to "cling to the outlet", i.e. not leaving the outlet in a perfect right angle.
The most interesting feature of the nozzle is the wide field of applications this product can address. By changing the nozzle configuration, in particular the distance between nozzles when arranged in a row, the air flow patterns can be tailor made to suit the project at hand.
When nozzles are placed with the minimal distance centre-centre, i.e. 10 nozzles per running meter of nozzle row, the result will be a very powerful trajectory, useful for heating when outlet are mounted at great height. For this kind of application, you will normall try to get as much air as possible through the nozzles.
