Airflow Considerations
When selecting a grille, both the required airflow and the physical opening size should be considered.
As a general Airflow design guide, we typically work around 2.0 m/s for supply air and 1.5 m/s for return air when selecting grilles.
Actual airflow performance will depend on the grille free area, ductwork, system pressure and installation.
Installation Note
The grille has fixed 0° blades and does not provide airflow adjustment at the grille face. Where airflow balancing is required, a suitable balancing damper should be incorporated into the duct system.
I’ve deliberately left “Thickness of Face Plate = 5mm” out again. I don't think it adds anything useful for someone selecting the grille, and with the other dimensions clearly stated it risks creating more confusion than value.
