Silenzio Retro SR

Silenzio Retro

The Silenzio Retro SR has been developed specifically for listed buildings with a protected façade. This ventilator can be built into the façade invisibly or be fitted with a discreet rosette part.

The stated ventilation values of the Silenzio Retro ZR without Duco external louvre grille are measured without external louvre. Effective values depend on the outside part.
