Rectangular silencers with baffles 100
SIREZ10 series silencers are absorption or absorption and resonance silencers with 100 mm baffles. They represent the best solution in terms of attenuation of midrange frequencies. The silencers can be used in civil and industrial air-conditioning systems with the aim to reduce the noise propagated through the ventilation ducts.
Noise attenuation passing through the distribution network, implies the reduction of the sound pressure level that reaches the terminal units and that is therefore spread into the environments treated.The sound levels caused by the ventilation system have to meet the requirements set by law, in accordance with their uses on the rooms.
The silencers can also be used to reduce noise emissions of the ejection ducts to the outside, wherever the environmental condition claims this by law.
