When retrofitting PV systems, it is not uncommon for an existing sanitary ventilator to be located in the middle of the roof. Then you have to do without a PV module and therefore also solar power. In the worst case, the solar installer even saws off the existing sanitary ventilator. Both can be avoided with the “flat PV sanitary fan” from Jacobi Walther!
Simply replace your existing sanitary fan with the flat version. The “PV sanitary fan flat” is made of robust die-cast aluminum and is available in all colors for all Jacobi Walther models (except: H1, H2, K1, Marko and Biber). The attachment is always in black.

Technical data:
Dimensions depend on the brick model chosen (note exceptions). The product does not reach the minimum height of 15cm required by DIN 1986-100.
Note: Please take into account the pollutant resistance of the back of the PV module according to the manufacturer’s instructions.
