Symbols and specifications
Ps = Static pressure loss in Pa
Q = Air Volume in m³/h
Type = Hole LXH in wall in mm
Vk = Effective air velocity true the grille in m/s
Ak = Effective area in m²
Lw(A) = Acoustic power in dB(A)
Note: Given values for louvers in exhaust. when used for air intake, the pressure drop will be higher up to 25% of the given value of Ps with an increase up to 4dB(A) in sound power.
