Rectangular silencers with baffles 100


Rectangular silencers with baffles 100Description

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.


Structure and dimensions


It’s made of galvanized sheet steel with stiffening ribs. For larger sizes the structure is strenghetened

Sheet thickness:

- 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.

Connection flange

Standard supply with  flanges on both sides

Flanges dimensions:

- 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.

Constructions with different flanges, without flanges, with flange on one side only or in stainless steel, on request.


Available in two types: standard and with aerodynamic profile, to reduce the pressure drop. Structural frame made of galvanized steel of thickness 0.8 mm. On request, more types are available.

Soundproof material

High density panels made of rock wool certified and Class "0" (non-combustible) reaction to fire (DM. 26/06/1984).

Baffle coatings

Standard glass fiber coupled abrasion-resistant and expanded mesh (up to a maximum speed of crossing 12 m/s).

Special coatings on request.


The silencers in the standard version can be installed in any position up to a height of 600 mm with a maximum depth of 600 mm.

Use condition
