The roof base fits the BRF/DV-ROF-R fans, which occurs in two versions of the winding insulation class B and F.
In the case of mounting the fan directly on the base, use the USZ gasket at the location where the fan gets into contact with the base.
The roof base can be provided at an angle of 1-60 degrees.
The base is insulated with wool with the thickness of 30 mm and 50 mm, depending on the size.
