Ruskin Company Grille Transfer Silencer GSV

The GSV Grille Transfer Silencer is constructed with a 22-gauge galvanized frame and features a perforated blade filled with inorganic glass fiber acoustic material, which is packed under 5% compression to prevent settling. It is designed to withstand a differential air pressure of 8 inches water gauge. The silencer has been tested for fire hazard classification, achieving a flame spread index of 20, a fuel contribution of 15, and a smoke developed index of 20 according to ASTM E84, NFPA 255, or UL-723 standards. In terms of acoustic performance, the GSV provides attenuation across various octave band mid-frequencies, with specific decibel reductions noted for frequencies ranging from 63 Hz to 8000 Hz. The product also offers variations including different flange configurations, lining options, and shell gauges, allowing for customization based on project requirements. The airflow-pressure drop characteristics are specified for various static pressures and face velocities, making it suitable for a range of applications in sound control.
