Airflow Performance

For the 600 × 150 RCBG246, the manufacturer's published performance data is:

Face Velocity	Airflow	Throw	Pressure Drop	NC
1 m/s	70 L/s	2.0 m	1 Pa	<15
2 m/s	140 L/s	3.2 m	4 Pa	<15
3 m/s	211 L/s	4.4 m	10 Pa	<15
4 m/s	281 L/s	5.6 m	17 Pa	15

Airflow at 2 m/s: 140 L/s

For typical supply-air sizing, 140 L/s at 2 m/s provides a useful design reference. Actual system performance will depend on the ductwork, available 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 installed within the duct system.
