CT-700L - Aluminum door return grille with sight-proof blades parallel to long dimension

The CT-700L is an aluminum door return grille designed with sight-proof blades running parallel to its long dimension. This unique construction effectively obscures the view into the ductwork or plenum while maximizing the free area for optimal airflow. Crafted from durable aluminum, the CT-700L is resistant to damage from impacts, making it suitable for high-traffic areas.

A key feature of the CT-700L is its inverted-V blade design. This configuration not only provides complete sightproofing but also adds significant rigidity to the grille structure. This ensures the grille maintains its shape and performance even under pressure or minor impacts. The combination of robust material and clever design makes the CT-700L a reliable and long-lasting solution for demanding HVAC applications.

While commonly employed as a door return grille, the CT-700L's versatility extends to various HVAC projects. It's an excellent choice for both exhaust and return air applications where concealing the interior ductwork is desired. Architects and contractors often specify the CT-700L for projects like schools, hospitals, and commercial buildings where maintaining a clean and aesthetically pleasing appearance is paramount without compromising airflow efficiency.
