Aduro Air booster
This package includes 1x fan for combustion and 4x60mm screws. This fan is mounted together with the existing fan and you thereby achieve a higher airflow having 2x fans mounted together. This solution can alleviate bad chimney, lack of air supply and contribute to a better combustion compared to having only 1x fan mounted.
Fan dimensions: 12 x 12 x 2.5 cm
