ClimaConnect aluminium external wall grille 400x300 mm

The ClimaConnect aluminium external wall grille 400x300 mm is a fixed aluminium grille designed for the passage of outside air through the façade. It is used in mechanical ventilation systems for residential buildings, offices, schools and commercial properties, ensuring controlled air supply from the external environment. Both the frame and the blades are made of aluminium. Behind the grille is a steel mesh with a mesh size of 2.3 x 2.3 mm that prevents insects and large debris from entering. The blades have a pitch of 33 mm and protect the air duct from direct rain ingress.

Advantages and features

• Aluminium construction: the frame and blades are made of aluminium, making the wall grille low maintenance and durable.
• Steel mesh with fine mesh size: the mesh behind the grille has a 2.3 x 2.3 mm mesh size, effectively keeping insects and large debris out of the air duct.
• Blades with 33 mm pitch: the uniform blade spacing ensures a well-distributed airflow and effective rain protection.
• Large free flow area: approximately 50% of the gross surface area is available for airflow, reducing pressure loss.
• Fixing with screws: the grille is easily and securely mounted in the wall opening using screws.
