AEROVAC sound attenuators are manufactured in many varieties, module sizes, and materials, including no-full models and models that eliminate acoustical fill entrainment into the air stream. Our industrial silencers are engineered for HVAC noise control in commercial industrial and institutional applications. Including hospital and clean room systems.
Standard attenuators are available in different models for traditional applications requiring broadband noise reduction. Performance data Is provided for four basic lenglhs-3′, 5′, 7′, and 10′. Units are also offered In 4′, 6′ , and 8′ 1engths.
Model HP is high-pressure drop unit ideally used for system velocity at or near 700 fpm.
Model SP is a standard pressure drop unit ideally suited for system velocities at or near 1,000 fpm.
Model Mp also provides excellent attenuation values along with a moderate pressure drop at somewhat higher air velocities.
Model LP offers the lowest pressure dn:lp for higher velocity Systems.
