        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.
