Rotating chimney cowl with external bearing serves for creation of additional draught in chimney ducts and protects them from unfavourable weather conditions, strengthens natural draught. Significantly increases the efficiency of the chimney system. It is the most attractive from the aesthetic point of view. Works without a power source, using wind energy.
The chimney cowl is mounted on the chimney at the top point of the chimney channel.
The draught efficiency can be increased by up to 20%!

Rotating chimney cowl with external bearing is made of stainless steel.
It is equipped with additional rotating elements - turbine head and blades.
The rotating mechanism uses a bearing that makes the blades rotate even in low wind flow.
