Vibro-Acoustics - Model ALV -V-Blade Acoustic Louvers

Acoustical Performance
Transmission Loss (TL) determined by ASTM E90. Noise Reduction (NR) may be determined iis: NR-TLi6. Insertion Loss (IL) may be estimated using: IL-TL+2 for all bands ot interest.

Aerodynamic Performance
Free Area and Pressure Drop determined by AMCA Standard BOOL for free inlet and outlet under ideal conditions. System effects due to ducted conditions, low height, or obstructions may increase pressure drop by a factor of 1.5 or higher.

Dimensions
Maximum single piece size: 60" x 120"; larger louver sizes will be multiple pieces. Minimum height: 12". Louver with less than 30" high, will require assistance with product selection to minimize risk of higher pressure drop values.
