Series 100-200
Table for forced ventilation based on a corrected face velocity of 2.5 m/s, which corresponds to a sound power level of 48
dB(A) when functioning as an extract
grille and 52 dB(A) as an fresh air intake grille, considering an area of 1 m
2
(use table
3, Sound Power Level Correction Table, to calculate other areas).
T
able 1. Quick selection tables
The free/frontal area of an air intake grille with dimensions LxH can be calculated as follows:
The frontal area would be A
f
(m
2
)=(L-0.014)*(H-0.109). The relation of this area to LxH will be the free area percentage.
Example: For dimensions 1000x800: A
f
(m
2
)=(0.986*0.691)=0.6813 m
2
. The area LxH in this case would be 0.8 m
2
so the
percentage of free area would be 84%.
