Double Deflection Curved Duct Supply Grilles

Engineered for Maximum Airflow Flexibility in Spiral Duct Systems

The AIROTEK AG-CDG double deflection curved duct grille is purpose-built for HVAC applications that demand high flexibility and precision airflow management within spiral or curved duct configurations. Its uniquely rolled frame is matched to the specific duct radius, allowing the grille to mount flush with the spiral duct surface — eliminating gaps and ensuring a clean, professional installation.

The dual-blade system provides full control over air distribution. The front horizontal adjustable blades govern the vertical throw of the airstream — typically directing cooled air upward along the ceiling for efficient room coverage. The rear vertical fixed blades handle horizontal spread, together delivering a precise and adaptable air pattern suited to diverse room configurations.

AIROTEK model AG-CDG also features an integral volume control damper with an opposed blade design. The damper is operated via a screwdriver slot, enabling easy airflow balancing without removing the grille — a significant advantage for both installation and ongoing maintenance.
