|About BRD HUSH DUCT™ Silencers:|
Schematic representation of series C circular silencers (top) and series R rectangular silencers (bottom).
|BRD silencers consist of parallel baffles or bullets constructed of perforated metal with rounded aerofoil design. The baffles are filled with sound absorptive material. A durable outside casing (solid sheet) provides the structural integrity of the unit while acting as a barrier to contain and reflect sound waves into the packed sections. Controlling the baffle and airflow passage thickness and spacing allows HUSH DUCT™ silencers to be tuned to reduce the most offending tones or frequencies. BRD sales engineers have the experience and knowledge to help you determine the requirements of your project and select hte most cost-effective standard or custom design for the application. Thin profile acoustical louvers (4" to 12") are available for building ventilation applications to/from mechanical equipment rooms.|
