Rectangular silencers with baffles 200
SIREZ20 series silencers are absorption silencers with 200 mm baffles. They represent the best solution in terms of good value for money. The silencers are used in civil and industrial air-conditioning systems with 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.
Structure and dimensions
It’s made of galvanized sheet steel with stiffening ribs. For larger sizes the structure is strenghetened
- 0.6 mm with the longest side up to 450 mm
- 0.8 mm with the longest side up to 750 mm
- 1.0 mm with the longest side over 750 mm
Construction in stainless steel or other materials on request.
Standard supply with flanges on both sides.
- 20mm with major side up to 1000mm
- 30mm with side greater than 1001 up to 2000mm
- 40mm with longer side over 2001 mm
On request: constructions with different flanges, without flanges, with flange on one side only or in stainless steel.
Available in two types: standard and with aerodynamic profile, to reduce the pressure drop. Structural frame made of galvanized steel with thickness 0.8 mm. On request, more types are available.
High density panels made of rock wool certified and Class "0" (non-combustible) reaction to fire (DM. 26/06/1984).
Standard made of glass fiber coupled abrasion-resistant and expanded mesh (up to a maximum crossing speed 12 m/s).
Special coatings on request.
The silencers in the standard version can be installed in any position up to a height of 1,000 mm with a maximum depth of 1,000 mm.
Maximum operating temperature: 250° C
