Single Deflection Return Grille

ICEMAC Single Deflection Return Grille (IC-SDRG Series)

Product Overview
The ICEMAC IC-SDRG Series is a high-efficiency return air grille designed for non-diffusive extraction in mechanical ventilation systems. It features a single row of manually adjustable aerofoil blades—available in horizontal (HF) or vertical (VF) orientation—for directional control of return airflow with minimal noise and pressure drop. Constructed from precision-engineered extruded aluminum, the SDRG series offers robust performance and seamless integration in ceilings, sidewalls, and return plenums.

Key Features

• Single Blade Row Design – Horizontal or vertical aerofoil-profiled blades for optimized airflow return.

• Tool-Free Adjustability – Blades allow manual tuning of return airflow angle to support system balance.

• Architectural Finishing – Available in RAL 9010/9016 or anodized/custom coatings to match interior aesthetics.

• Mounting Versatility – Supports screw, concealed screw, plate spring, and subframe installations.

Variants

• IC-SDRG-HF – Horizontal Front Blade: suited for ceiling and wall returns with lateral airflow.

• IC-SDRG-VF – Vertical Front Blade: optimized for return ducts requiring upward or downward deflection.

Applications

• Ceiling-Mounted Return Zones – Open-plan commercial areas and corridors.

• Wall-Mounted Return Points – Efficient extraction along perimeter zones or partitioned rooms.

• Mechanical Rooms & Plenums – Quiet return airflow with minimal static pressure impact.

Accessories

• OD / PD Dampers – Opposed or parallel blade dampers for return volume control.

• Plenum Boxes (PB) – Smooth airflow transition and noise attenuation.

• Subframes (SF) – Precision seating for recessed grille applications.
