The mounting plate for the fan for roof bases serves the purpose of the bottom mounting at the PDI-BRV/PDI-S-BRV base, in order to use the base as the thermal and acoustic insulation.
Fix the plate to the base using WGO screws, the site where the plate joins the base, must be protected by the SIL-DEK-310 roofing sealant.
Rivet nuts match the size of the FLS flange.
The roof base fits the DV-ROF-V fans, which occurs in two versions of the winding insulation class B and F.
