Differences between chimney bonnets and ECCO

Can water enter through the ECCO Extractor?

No. Its design stops water from entering. There is a gyratory chimney bonnet on the market which has a similar mechanism, but which does let in water.

ECCO manufactures wind turbine extractors with hidden vanes and with three clefts which direct the drops outwards, stopping the entry of water.
