AIR 28
Weighted sound reduction index up to Rw = 28 dB(A)
Burglary resistance up to RC3
Fire resistance up to 60 minutes
The AIR 28 acoustic louvre is the ultimate solution for ventilation and façade projects where superior noise reduction must go hand in hand with optimal airflow. With a 28% free area and high-density internal acoustic material, the louvre delivers efficient ventilation combined with effective broadband sound attenuation. Its aerodynamic louvre profile minimises pressure drop and, depending on size and configuration, can reduce noise by up to 28 dB(A) without compromising performance.
Constructed from robust galvanised or stainless steel and finished with durable coatings, the AIR 28 louvre ensures long-lasting performance even in demanding outdoor environments. The high-density internal acoustic material maintains consistent performance under varying weather conditions and humidity levels. Optional accessories, such as bird mesh, filters or protective grilles, can be added to meet specific project requirements.
Manufactured in compliance with ISO 9001, the louvre guarantees reliability, safety and consistent noise reduction in any application.
The AIR 28 louvre is perfect for façade openings, ventilation ducts, machinery rooms, and technical enclosures. It can be installed vertically or horizontally and easily integrated into air intake and outlet systems or wall sections. Dimensions and finishes can be fully customised, making it ideal for both new-build and renovation projects where high levels of noise reduction, security and fire safety are essential. With the AIR 28 louvre, you choose maximum performance and comfort.

Answers to common questions
Merford louvers are aerodynamically designed to minimize pressure drop and guide airflow efficiently. This ensures ventilation performance remains high even at increased airflow.
Yes. The frame and blades are made from galvanized or stainless steel with durable coatings, and the internal fill is moisture‑ and weather‑resistant, ensuring consistent performance under varying weather conditions.
AKR louvers are mainly designed for sound attenuation and ventilation. AIR louvers combine acoustic performance with additional safety features, such as fire resistance and burglary resistance (RC class), making them suitable for critical or secured environments.
