Meet the Intense-Air. A high-capacity linear bar wall grille built to move maximum air through an 18" x 18" opening. Seven wide steel bars plus a full perimeter slot deliver far more airflow than a standard louvered or plastic grille, while keeping a clean, modern flush-mount face.
Key Features:
Material: 1.2mm (18 ga) Cold Rolled Steel
Finish: Scratch-Resistant Powder Coating
Duct Size: Fits standard 18" x 18" wall openings
Application: Supply Air or Return Air (Wall only)
Intense-Air Face: Seven linear bars plus a full perimeter slot, 48% open area for high air delivery.
Maximum Airflow: About 3x the net free area of our standard 18x18 grille, so it moves far more air at the same static pressure.
Hidden-Screw 2-Part Design: Flush-mount steel grille with no visible fasteners for a seamless look.
Paint-Ready Matte Finish: Comes in powder-coated Matte White, ready to match any interior.
