SD – SILENCERS FOR RECTANGULAR DUCTS
The SD silencers are designed for efficient noise attenuation in rectangular ventilation ducts. Ideal for quiet zones, they pair seamlessly with insulated fans to meet strict acoustic requirements.
The SD series silencers are specially engineered to reduce noise levels generated by ventilation systems and transmitted through rectangular ductworks. These silencers are essential for use in offices, medical centers, residential buildings, and other environments with strict acoustic standards.
Constructed with a durable galvanized steel casing and sleeves, SD silencers are available for duct sizes ranging from 400×200 mm to 1000×500 mm. They are designed to be used in combination with sound-insulated fans, providing a complete solution for quiet ventilation setups.
Thanks to their robust build and effective sound-dampening performance, SD silencers help maintain indoor comfort without compromising ventilation efficiency. They are particularly valuable in noise-sensitive areas where a quiet and peaceful indoor atmosphere is essential.
