Series A Noise Attenuation Orifice Plate

Brand: Watson McDaniel

Series A orifice plates are custom engineered to maximize noise attenuation and reduce dbA to the lowest achievable value. 

The number and diameter of holes will be determined based on application conditions, and the plate diameter will typically be equal to the recommended downstream pipe size.
