|
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
|
|
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.

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 can 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.
