When project space limitations cannot accommodate straight silencers, Rectangular Elbow Film-Lined (“REFL”) silencers can be used to both reduce noise and control pressure losses.
To save space and reduce project cost, any silencer can be designed to have different connections and casing geometry to match project requirements.
Vibro-Acoustics can provide duct silencers to match project requirements for space and configuration limitations – virtually any size or shape is possible.
