Acoustical Louvers are used as part of the intake/exhaust air system of buildings, structures, or equipment to help reduce noise produced by the system equipment. They have a relatively large surface area which compensates for their lack of depth. Models are available in varying depths, percent open area and blade configurations yielding various pressure loss and noise reduction performance.
