Symbols and specifications
LxH = Width L and height H in mm
Q = Air volume in m³/h
Ak = Effective surface (free area) in m²
Vk = Average effective velocity through the grille in m/s
Y0.25 = Vertical throw in m at an end velocity Vt of 0.25 m/s
Ps = Static pressure loss in Pa
Lw(A) = Acoustic power in dB(A)
The values are given for isothermal supply air without coanda effect.
The pressure losses Ps are given for grilles without damper or with fully opened damper.
The acoustic powers Lw(A) are given for grilles without damper or with fully opened damper without room attenuation. Acoustic powers below 20dB(A) are mentioned as "<20" in the tables.
For all other special requirements, please contact our engineering office.
