Construction of the base of the chimney draft provides support for gravity by creating a vacuum in a situation when the wind blows root.
It always sets the direction of the wind, shielding the same hole chimney.
Used both for ventilation chimneys and flue.

The mechanism consists of stainless steel material A.I.S.I 304 and includes Bearings. Bearings immersed in a grease bath to provide superior lubrication.

Rotary chimney cowl with external bearings is a device, which, in a dynamic way, uses force of the wind to increase chimney draught. The turbine always rotates in the same direction no matter of the wind strength or its direction.Thanks to the patented bearing system placed outside, the influence of exhaust gases is minimised and the cowl can be used with gas – fired applications. It is recommended for flue ducts. Recomended usage: – when there are wind fluctuations on the chimney duct ending, caused by its bad location – when there is an unfavorable terrain configuration, with strong and frequent winds – when there is a lack of chimney draught or it is too weak – in order to improve the natural (gravitation) chimney draught in flue ducts Features: – Rotating unit: greased ball bearings, placed outside the turbine – Withstands flue temperatures up to 500°C.

Supplied fully assembled and ready to fit.

Has a CE certificate; – Highly effective at preventing downdraught and increasing ventilation.

Suitable for all fuel types; – Detailed diameters on picture;.
