Primary air fans, forced draft fans, and induced draft fans generally require some form of acoustical treatment. Most applications require inlet andor outlet silencers to meet Noise Standards and other noise requirements. For continuous exposure, a maximum of 90 dBA is generally specified to avoid hearing damage. When conversation near the fan is desired, levels of 80 dBA and less are often needed. We designs and manufactures a complete line of silencers for application on all fan types. Computer-enhanced technology developed for fan, turbine, and other air-moving equipment enables Us do offer a cost-effective solution to every fan silencing application. We offers four designs, each with unique advantages, depending upon application-specific requirements for octave band attenuation, pressure drop, and space utilization.
