Rotatable chimney coals for ventilation ducts and chimneys.
Ventilation duct spigot diameters DN 150 – 300 mm. The bases are made of aluminium.
Rotatable chimney coals are used to improve the air flow by using the wind power. The swing deflector pivots in one direction regardless of the direction and strength of the wind and prevents reverse draught.
The second purpose of the rotatable chimney coals is to protect the chimney from precipitation of combustion and moisture.
