Product Application
Every air distribution system requires a return grille to ensure a constant outflow of air. Our CR510U grilles are the best in the market because of their versatility and durability. With the core and frame constructed using high-grade aluminum, these grilles can be used in environments that require heavy usage. The U-frame allows an option to install a damper which further ensures the noise levels are kept at a minimum during peak operation. These grilles are perfect for libraries, large study rooms and conference rooms.
