Aphonic grids of the SIL-grid series meet the requirements for noise attenuation in both ventilation systems and industrial applications. In ventilation systems, they can be used as a replacement for common industrial grids, either in the intake or exhaust direction. This provides the advantage of having a single component that fulfils a dual function: on the one hand, it protects the outside air intake like any industrial grid, and on the other hand, it reduces the noise emissions to the outside environment produced by the ventilation system like any silencer.
In addition to the simple S version, a double D version with two grids mounted back-to-back is available if higher abatement is required.
In industrial applications, aphonic grids can be used in walls in either the simple or double version.
They find their application in the construction of enclosures, cabinets or technical compartments and, more generally, in all those applications where both air transit and adequate noise attenuation must be guaranteed. In addition to the standard series, special constructions can also be supplied to customer specifications.
