1 Acoustic Shield Natural Ventilation Acoustic Roof Vents Compact Design BB101 & 93 Standard / Twin Flow / Mixed Mode natural ventilation roof vents can be finished in any colour to compliment the architectural appearance of the building while meeting Part L2 & BB93 & 101. The integral Acoustic Shield sound reduction system allows this unit to be used in close proximity to external noise sources including road, rail and airports. Available in 3 sizes with various configurations the Phoenix range can be integrated with most roof mounted commercial acoustic natural ventilation applications. Standard Specification: Acoustic Natural Ventilation Roof Vents include sound insulation and Acoustic Shield technology to reduce rain drumming and increase sound absorption using a specific design configuration of high density non hygroscopic HFC & CFC free acoustic foam. Main body of unit made in galvanised sheet steel powdered coated in Goose Wing Grey 00A05 as standard (Any RAL colour can be specified) with weather proofed overlapping slopes to prevent water pooling on roof vent. Integral bird mesh (optional additional stainless steel insect screen) with internal wind driven rain and snow barrier. 24V actuators factory fitted to integral insulated tight seal dampers. Where boost fan fitted Specific Fan Power S.F.P. = 0.25 W/l/s. Wind Assist Warm stale air exhausts via Phoenix roof vents Cool fresh air enters via Natural wall vent/window
