External wall louver, DN 250 intake/exhaust 990430587

Ventilation with class – external wall louvre Zehnder DN 250

This external wall louvre from Zehnder, with a diameter of 250 mm, is a component of a ventilation system that provides fresh air to the room. It is designed for use as an air inlet or outlet, making it a versatile solution in ventilation installations.

Design and application

This louvre is designed for outdoor mounting, enabling effective air exchange while maintaining an aesthetic appearance. Thanks to its construction, it provides optimal airflow while protecting the interior from atmospheric precipitation and contaminants. It is suitable for both new buildings and the modernization of existing ventilation systems. Installation is relatively simple and does not require specialized tools – just a properly prepared place on the facade.

Advantages and benefits

• Versatility: It can function as both an air inlet (supply air) and an outlet (exhaust air).
• Protection against the weather: The louvre design minimizes the risk of rain, snow or leaves entering the ventilation duct.
• Aesthetic appearance: The external Zehnder louvre integrates with the building's architecture without disrupting its aesthetics.
• Durability: Made of high-quality materials, it guarantees long-lasting and trouble-free operation.
• Warranty: The product is covered by a 2-year manufacturer's warranty, confirming its high quality and reliability.

It is worth remembering that choosing the right louvre diameter (in this case DN 250) is crucial for the proper functioning of the entire ventilation system. Too small a diameter can restrict airflow, and too large a diameter can generate unnecessary noise.
