Silencers for ventilation duct, ø 250 mm, L = 90 cm

The Silencers of VENTILUTION® are used for noise absorption generated by the ventilation units and spreaded by the air ducts of the ventilation systems. They are also suitable for pit and inserted ceiling installations and remarkably reduce the noise level. If you want to reduce the noise level not only in the air ducts but also on the device itself we recommend a sound insulation case.

Design:

• The galvanized steel casing is filled with flameproof sound insulating material
• Equipped with protecting covering against fiber blowing-out and connecting flanges with rubber sealing for airtight connection to the air ducts

Mounting features:

• The design allows fixing it on the round ducts in any position by means of clamps
• The linear mounting is preferable for to attain the better effect
• To prevent the flexible silencer sagging it should be fixed not only at the ends but in the middle
