Details
Engineered for precision airflow control, these 6x18 inch double deflection supply air grilles and registers feature independently adjustable blades to direct ventilation exactly where it’s needed. The horizontal front blades manage vertical airflow (up/down), while vertical rear blades handle side-to-side distribution—giving HVAC installers and architects complete command over comfort conditions. These heavy-duty registers work equally well in sidewall, ceiling, or duct applications, making them ideal for commercial HVAC systems where customizable air patterns matter. With their high free area design, they maintain strong airflow while reducing whistling and pressure drops—critical for quiet, efficient operation. Unlike standard supply grilles, the dual-adjustment system prevents drafts by letting professionals fine-tune both the throw distance and spread pattern. Whether retrofitting existing spaces or designing new installations, these adaptable air registers solve common airflow challenges without sacrificing performance. Professional installation recommended.
- Precision 6x18" Duct Opening: Engineered for a perfect fit on standard 6x18” ductwork, this double deflection grille ensures optimal compatibility for a seamless HVAC integration. Please confirm exact measurements with our sizing chart.
- Superior Airflow Control: Features front horizontal blades for precise, multi-directional airflow management, allowing you to expertly direct comfort where it's needed most.
- Prevents Ceiling Stains: A built-in weather-stripping gasket stops air leaks, shielding your ceiling from dust buildup and ensuring optimal airflow direction.
- Clean, Architectural Aesthetic: Designed for a flawless look with no visible pre-drilled holes. Fastening is discreetly located on the inner border sides to maintain the grille's sleek, modern profile.
- Commercial-Grade Aluminum Build: Constructed from solid extruded 6063-T5 aluminum, this heavy-duty air register is built for exceptional durability and reliable, long-term performance in demanding environments.
- Durable Matte White Finish: Coated with a strong matte white powder coat that provides superior resistance to fading, corrosion, and everyday wear, ensuring the finish lasts.
- Flexible Installation Options: This grille is supplied without fasteners to provide installers with the flexibility to choose the best mounting hardware for their specific substrate and project requirements.

Decoding "Commercial-Grade" for Your HVAC Specifications
For architects and engineers, specifying true commercial-grade HVAC components involves more than just finding a durable product. It's about securing a partnership that provides deep technical support to guarantee your design functions perfectly. This requires complete clarity on material composition and, crucially, certified performance metrics. Essential data includes acoustic levels (NC ratings), system pressure drop, and accurate CFM airflow numbers.
Trust is built on proof, not promises. That's why our air distribution products undergo rigorous independent testing to comply with strict industry standards such as ASHRAE 70-2006 and ADC1062:GRD-84. We go a step further by integrating advanced computer simulations in our design process. This allows us to refine the aerodynamics and energy performance of our modern linear bar grilles and diffusers long before manufacturing begins.
For high-performance air distribution solutions you can count on, Flo-Matrix HVAC has been a leading manufacturer for years. We focus on commercial-grade diffusers and linear grilles engineered for the most challenging environments. Have a project on the boards? Our product experts are here to assist.
