A ventilation silencer designed to reduce noise in central duct systems, promising straightforward retrofitting for quieter rooms. Peaceful living spaces and fewer distractions for offices, workshops and communal areas. Is neverest ESD Duct Silencer the cost-effective answer for 100mm round ventilation pipes?
⚡ At a Glance
- • Sound Reduction: Absorbs and dampens road and airflow noise when fitted in 100mm round ducts, with greater effect when multiple silencers are used in sequence
- • Best for: Residential homes, offices and industrial buildings seeking simple duct-borne noise mitigation
- • Not ideal for: Duct systems other than 100mm round runs or situations needing full-room acoustic treatment
Designed to fit 100mm round ducts with a 50mm depth, made from polyurethane foam with oval openings and releasable plugs. Sequential placement of several silencers along a duct run improves overall attenuation.
Quieter interiors, with polyurethane foam absorption
Polyurethane foam absorbs airborne sound within its cellular structure, reducing reflected noise in ductwork and limiting transmitted airflow noise. The porous structure traps and dissipates energy from sound waves rather than reflecting it back into rooms.
Noticeable reduction of road and ventilation noise inside rooms served by the ductwork, improving comfort without extensive construction work.
Quick retrofitting, with simple insertion and releasable plugs
Oval access openings with releasable plugs allow holes to be prepared and the silencer to be inserted directly into the duct, eliminating the need for major modifications. The shallow 50mm depth keeps the unit compact for in-line fitting.
Fast installation after opening the required holes, making it a practical option for upgrading existing systems without full duct replacement.
Scalable silencing, with modular placement along ducts
Placing multiple silencers in sequence increases cumulative attenuation, enabling installers to tailor noise reduction by location and number of units. Strategic positioning near noise sources or along long runs improves overall performance.
Ability to tune performance by adding extra silencers, useful for louder installations or where targeted noise reduction is needed.
