The limit of 3 m/s is due to the waterproof characteristic. The laboratory tests, have shown that up this limit the water drops go down due to gravity while for velocities between 3,2÷3,5 m/s the water drops go up and to begin to go beyond the grille. This phenomenon increases with velocity increase.
