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 plenum velocity to medium velocity applications. Rectangular silencers are available in galvanized steel, paintable steel, 304 and 316 stainless steels, and aluminum.

Standard
Round Silencers
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.
