Ozone 20" x 30" (Wall Opening Size) Sidewall/Ceiling Return Air Grille (White)

The Ozone 20" x 30" (Wall Opening Size) Sidewall/Ceiling Return Air Grille (White) is a heavy-duty, high-capacity return vent designed to efficiently pull air back into your HVAC system for recirculation in residential or commercial setups.

This large-format grille features a classic fixed bar design (non-adjustable louvers) that allows unrestricted, high-volume airflow with minimal resistance—essential for return air paths to maintain balanced system performance, reduce strain on your blower, and improve overall energy efficiency.

Key Features:

• Generous sizing — Precisely fits 20" x 30" wall or ceiling openings (duct/wall cutout), providing ample intake area for effective air return in medium to large rooms or zones.
• Durable construction — Made from sturdy stamped steel for long-term strength, warp resistance, and reliable use in high-traffic areas.
• Clean, versatile finish — Smooth white powder-coat that resists chipping, corrosion, and yellowing, blending seamlessly with walls or ceilings for a professional, unobtrusive look.
• Dual-purpose installation — Ideal for sidewall (wall mount) or ceiling applications, with a flush or semi-flush design that sits neatly over the opening.
• Easy maintenance — Open-bar style promotes free airflow while allowing simple cleaning; compatible with optional filter frames if needed for added dust control.
