The DM84 Tapered Rectangular Silencer from Ruskin Company is designed for effective sound control in HVAC applications. It features a tapered pod design that enhances airflow efficiency while minimizing pressure drop. The silencer is constructed with an acoustically transparent perforated liner and acoustical grade fibrous media, which contribute to its medium dynamic insertion loss performance. The product is available with a 1-1/2" slip flange for easy installation. Performance data indicates that the DM84 can achieve significant insertion loss across various octave bands, making it suitable for environments where noise reduction is critical. Static pressure drop values are measured in accordance with ASTM E-477 standards, ensuring reliable performance under specified conditions. This silencer is ideal for engineers seeking a balance between sound attenuation and airflow efficiency in their projects.
