Ahead about wave-length in micro drizzling

By a water jet in a tube air becomes aspirated and accelerated. The accelerated air entrains generated water drops by leaving the tube. By means of big air volume and high air speed the IDS-Jet nozzle is able to transport the microsized water drops about 6 to 18 m through the air.


Throwing range about 16 m, water consumption 11 l/min, jet nozzle about 7 m over ground, resultant water surface 2.000 m²
