AR

Description

The ARO / ARE industrial backdraught dampers are designed to automatically prevent air backflow in industrial ventilation systems. Operating by gravity, the blades open under the effect of the airflow and automatically close when the airflow reverses, ensuring one-way air circulation.

Thanks to their robust industrial design, high resistance to back pressure, and wide choice of materials (stainless steel, aluminium, ATEX), ARO / ARE dampers are ideally suited to demanding industrial applications.

Available in galvanized steel, stainless steel, aluminium, or painted steel, they meet the requirements of ventilation systems exposed to high mechanical loads and harsh operating environments.

Thanks to their modular design, AR dampers can be easily installed in rectangular ductwork for commercial buildings, technical rooms, and industrial facilities.
