Example of selection The selection graphs contained in this catalogue for the different models allow you to use the supply air flow and a maximum velocity in the occupied area (Vz) to calculate the following parameters: - Throw achieved by the air vein for a maximum air velocity in the occupied zone (Vz). - Total pressure drop and sound power level generated in the plenum-diffuser assembly. - Velocity (VhR) at a distance hR from the ceiling below the point where air jets meet. - Velocity at the wall (VL) at a distance hR from the ceiling. The methodology is explained below with an example:...
