Jet nozzle diffusers are most suitable when large spaces.
They are often used in concert halls, museums, theatres, shopping centers, airports etc.
The up to 45 degrees possible inclination of the jet helps directing the air to the right places.
The diffusers are very efficient for both hot and cold air and they can be directed down or up accordingly to the supplied air temperature.
Throws of more than 20 meters can be achieved.
