The patented saddle nozzle SD-45 is ideally suited for accomplishing high penetration depths or for aerial shielding of sensible areas similar to a separation jet system. The nozzle is suitable for creating concentrated jets at high flow rates with very low sound power levels. Any individual nozzle can be pivoted up to 20° and is available as modular construction. The SD-45 is very versatile; it can be used as a jet nozzle, for shielding and in special construction.
