The SEVi Silent 160 ULF sound-insulated fresh air diffuser is a product variant of the fresh air diffuser for maximising external sound insulation. Depending on the requirements, special sound attenuation inserts, a sound-optimised inner cover and a flat duct as a deflector are implemented in the system. As a result, standard sound level differences (Dn,e,w) of up to 66 dB can be achieved with 2 deflectors.
The SEVi Silent 160 ULF decentralised ventilation system – sound-insulated fresh air diffuser – facade deflection can be individually adapted to your project and the object situation and optimised in terms of sound technology. The SEVi Silent 160 ULF sound-insulated fresh air diffuser is ideal for your soundproofing projects.
The SEVi Silent 160 ULF sound-insulated fresh air diffuser as a reveal version consists of a fixed pipe (Ø = 160 mm) made of PPs (polypropylene) of low flammability and a flat duct, for installation of the ventilation system in properties with a wide range of wall thicknesses. A stainless steel weather protection grille forms the facade closure, and inside there is an inner screen that can be removed from the wall without tools. Sound insulation inserts are located in the fixed pipe to maximise external sound insulation.

The ULF variants allow the external closure of the ventilation system to disappear discreetly into the facade. The solution for demanding exterior facades; in addition, a particularly high level of sound insulation can be achieved with the ULF variants. This type of external closure can be individually adapted in its external dimensions for the respective project and is suitable for various facades (ETICS, clinker facades and others...).
