Stainless steel spherical rotating nozzle Ø200 NOK200N

Rotating chimney cap supporting gravity draft

The cap rotates in response to wind direction, utilizing wind energy to create negative pressure in the ventilation duct. It operates without electricity, requires no maintenance, and needs no intervention after installation.

Protects against rain and snow ingress

The spherical shape seals the chimney outlet, preventing moisture and contaminants from entering the duct interior. No additional covers or flaps are required.

Connection Ø200 mm — compatible with standard outlets

Designed for installation on duct ends with a diameter of 200 mm. Installation does not require modification of the existing system if the outlet has the appropriate size and shape.

Made of stainless steel sheet

The product is manufactured from high-quality stainless steel sheet, enhancing corrosion resistance and long-term durability. Specific alloy designation (e.g., 1.4404), sheet thickness, or other chemical parameters are not provided in the data and are therefore not listed.

Rotating mechanism with ball bearings

The cap features oil-immersed ball bearings, ensuring smooth, quiet, and reliable rotation even at low wind speeds. This is a critical functional component — it is not a static element.

Polish-made product

Manufactured in Poland, ensuring consistent quality and availability of spare parts.
