Product Details

An aluminum double deflection grille is a ceiling or sidewall HVAC air vent fitted with two rows of independently adjustable blades — a horizontal front blade and a vertical rear blade. Together they allow 4-way directional airflow control, which makes it the standard choice for supply air outlets in hotels, offices, hospitals, shopping malls and high-end residential projects.

Unlike a single deflection grille that only directs air in one plane, the double layer louver mixes supply air in both directions, delivers a longer air throw and reduces cold drafts on occupants. The frame is extruded from 6063-T5 aluminum alloy, then finished with electrostatic polyester powder coating in matte white RAL9016.
