Silent Elbow

The PAC Acoustical 90 is a 90-degree radius elbow engineered as a sound attenuation device. Developed for installation in the company's automated trim, scrap and waste handling systems, it reduces sound pressure levels created during the cutting and evacuating of film, foil, laminate, paper and other materials by 30-50 percent when tested against traditional sound attenuation devices set around straight length ductwork.
