JN-TG, aluminum jet nozzles, are developed for large and high areas. They are designed for areas such as concert halls, theatres, museum, airports, shopping centers etc. Because of their aerodynamic design, they give a long throw of air flow even at high outlet velocities and reduced noise levels. The jet can be adjusted over 360º. As these jet diffusers handle different supply temperatures, the jet can be oriented upwards or downwards (heating or cooling mode).
