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. Contact McGill AirSilence for assistance.
EFFECTIVE AND PREDICTABLE NOISE CONTROL FOR INDUSTRIAL AND HVAC APPLICATIONS
McGill AirSilence offers a complete line of Sounpak silencers for noise control in industrial and HVAC applications. Sounpak silencers have been designed, tested, and manufactured to ensure the highest performance and most efficient operation at an economical price.
McGill AirSilence has conducted acoustical testing programs on all Sounpak silencers. As a result of these tests, (run in accordance with ASTM standard E477), reliable and accurate performance data is available. This data allows the performance of Sounpak silencers to be easily and accurately predicted, and makes it possible to select the proper model and size to meet specified noise reduction requirements.
The performance ratings are available in easy-to-use tabular form by contacting McGill AirSilence or one of its local manufacturers' representatives.
Specialized construction features are available for all McGill AirSilence rectangular and round silencers.

STANDARD RECTANGULAR SILENCER MODELS
Rectangular, straight silencers are available in 3-, 5-, 7-, and 10-foot lengths. Both passive (acoustic filled) and reactive silencers are offered. Passive silencers may be ordered with a vapor barrier film between the fill material and the baffle wall. These silencers are good for low plenum velocity to medium velocity applications. Rectangular silencers are available in galvanized steel, paintable steel, 304 and 316 stainless steels, and aluminum.
Model Type Description
Type RSF Rectangular, straight, passive silencer with acoustical fill
Type RSV Rectangular, straight, passive silencer with acoustical fill and a vapor barrier
Type RSN Rectangular, straight, reactive silencer, no acoustical fill required
Type REF Rectangular, passive elbow silencer with acoustical fill
Type REV Rectangular, passive elbow silencer with acoustical fill and a vapor barrier
Type REN Rectangular, reactive elbow silencer, no acoustical fill required
Type RWF Rectangular, wide body, straight, reactive silencer with acoustical fill
STANDARD ROUND SILENCER MODELS
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.
Model Type Description
Type CSF Circular, straight, passive silencer with acoustical fill
Type CSV Circular, straight, passive silencer with acoustical fill and a vapor barrier
Type CSN Circular, straight, reactive silencer, no acoustical fill required
Type CEF Circular, passive elbow silencer with acoustical fill
Type CEV Circular, passive elbow silencer with acoustical fill and a vapor barrier
Type CEN Circular, reactive elbow silencer, no acoustical fill required
