Silvent supplies safety silencers developed to handle large airflow. These silencers can also be used in constant flow applications or as a central silencer for many valve simultaneously. The safety silencer`s built-in warning indicator allows you to avoid costly and unnecessary production stoppage. The unique filter is divided into numerous "sound traps" or cells that provide excellent silencing properties as well as extremely good air permeation. The silencers are available with 1" or 2" connection and provide noise suppression of approximately 40 db [a].These safety silencers indicate when backpressure becomes too high in the system due to contaminated clogging of the filter.
