      ICEMAC Round Duct Grille (IC-RG Series)

      Product Overview
      The ICEMAC IC-RG Series Round Duct Grille is a high-efficiency terminal device specifically engineered for direct installation into circular duct systems. Designed to perform in both supply and return air applications, it features individually adjustable blades in single or double rows to provide precise directional airflow. The grille’s compatibility with curved duct profiles and low pressure drop design ensures seamless mechanical integration and optimized performance in commercial and industrial HVAC systems.

      Key Features

      • Adjustable Blade Rows – Available in single or double configurations for supply or return control.

      • Duct-Radius Customization – Can be manufactured to match the curvature of circular duct systems.

      • Durable Aluminum Build – Entirely made from extruded aluminum profiles for strength and corrosion resistance.

      • Simple Installation – Screw-mounted directly onto duct surface for secure and vibration-free operation.

      • Variants Available

        • IC-RG-S: Supply grille with directional air throw.

        • IC-RG-R: Return grille optimized for low resistance air extraction.

      Applications

      • Circular duct supply and return systems

      • Exposed mechanical ceiling designs

      • Retail centers, industrial halls, commercial buildings

      • Stairwell ventilation, high wall air distribution

      Advantages

      • Directional Air Control – Individually adjustable blades offer tailored airflow delivery.

      • Architectural Compatibility – Matches exposed ductwork and modern HVAC layouts.

      • Low Pressure Drop – High free area reduces load on ventilation equipment.

      • Optional Damper Integration – Available with opposed blade damper (OD) or parallel damper (PD) for volume control.
