Model Standard Round -Silencers

SHARE

Circular (round) silencers are available in standard inner diameters of 12 to 60 inches. The length varies as a condition of pressure and insertion loss requirements. Applications include low- to high-velocity systems. Passive silencers may be ordered with a vapor barrier between the fill and the baffle wall. Circular silencers are available in galvanized steel, paintable steel, 304 and 316 stainless steels, and aluminum.

Sounpak Industrial and HVAC Silencers
Depending on the model, standard Sounpak silencers are manufactured in straight or elbow configurations and in round or rectangular shapes. They come with or without bullets or baffles and with or without acoustical fill or a vapor barrier and fill. There are models to handle airflow velocities from 0-10,000 fpm.

SPECIAL APPLICATIONS
McGill AirSilence also designs and manufactures Sounpak silencers for specialized applications where rigid design and noise reduction criteria, unique space limitations, adverse environments, or other special considerations preclude the use of standard models.
