Reactive (No Media) Silencers
VAW Systems’ RSR (Rectangular), RER (Elbow), CSR (Circular) and CER (Circular Elbow) reactive silencers are specifically designed for noise control in HVAC systems that prohibit any glass fiber fill. With smooth radius inlets and tapered outlets, maximum attenuation at the lowest possible pressure loss is assured.
Features include:
- Inlet and outlet connections matched to actual duct dimensions to avoid the need for transitions.
- Excellent balance between acoustic and aerodynamic performance.
- Constructed with materials that are suitable for corrosive or moisture laden airstreams.
- May be tuned at a key frequency(s) in order to address problematic tones in existing air systems.
