Rotary Chimney Cowl

Intended use:

Chimney cowls are elements ending the outlet of chimney flues.

The purpose of the cowls is to protect against wind, downdraught and support the draught when it is insufficient
They are used on gravity action chimney flues, such as smoke, combustion and ventilation.

The advantages of chimney cowls:
  • They prevent downdraught. They protect the draught during wind gusts.
  • Ball bearing rotation axis guarantees a very silent operation.
  • Easy installation - self-assembly ability
  • The unique look of stainless steel.
  • Very long lifetime.
  • The surface does not require any maintenance or corrosion protection.
Chimney cowl Sphere type

Designed mainly for ventilation flues. The force of the wind sets it into axial-rotation motion. The energy created as a result of such action causes an pressure increase in the ventilation flue, necessary for the proper discharge of ventilated air. The use of a Sphere type cowl also prevents downdraught. The use of high quality ball bearings ensures trouble-free operation throughout the entire warranty period and long after.

Chimney cowl Fireman type

The self-adjusting, "protecting" cowl is especially recommended for combustion, smoke and ventilation flues. The cowl automatically adjusts itself to the proper angle towards the wind, thus preventing chimney downdraught. The specific and original structure also supports the pressure, thus improving the smoke discharge from the chimney’s flue.
