The SEVi 160ALD sound-insulated fresh air diffuser as a reveal version 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 67 dB can be achieved with one deflection. The technical parameters change depending on the product configuration (see the technical data of the individual product configurations).
The SEVi 160ALD decentralised ventilation system – sound-insulated fresh air diffuser – reveal version can be individually adapted to your project and the object situation and optimised in terms of sound technology. The SEVi 160ALD sound-insulated fresh air diffuser as a reveal version is ideal for your projects in the area of sound insulation.
The SEVi 160ALD 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 variety of wall thicknesses from 320 mm. A stainless steel weather protection grille forms the façade closure, and inside there is an inner screen that can be removed from the wall without tools. The fixed pipe contains sound insulation inserts to maximise the external sound insulation.
The SEVi 160ALD can be completely closed. Even at 50 Pa over/under pressure, no leaks could be detected in the closed state.

The reveal variants allow the external closure of the ventilation system to disappear discreetly into the reveal. The solution for sophisticated exterior facades; in addition, a particularly high level of sound insulation can be achieved with the reveal variants.
