Details

This 16-inch linear slot diffuser delivers both aesthetic appeal and performance with its crisp matte white finish. Unlike inferior alternatives, it's crafted from heavy-duty extruded aluminum - identical to the premium material specified for high-end commercial installations. This vent cover excels at maintaining consistent airflow in your environment while offering precise control for VAV applications through its 19mm slot opening and 180-degree adjustable blades. (See our airflow visualization video for performance verification in the videos section.) We recommend professional installation by qualified HVAC technicians for optimal results.

 

  • Precision Size & Design: Features a clean 16" x 1.5" nominal size with a sharp ¾" (19mm) slot opening for a sleek, modern aesthetic. (Please refer to the size diagram for detailed dimensions).
  • Eliminates Ceiling Smudges: An integrated weather-stripping seal prevents air leakage, protecting your ceiling from unsightly dust marks and ensuring all air is directed through the diffuser.
  • Durable, Commercial-Grade Construction: Built from heavy-duty 6063-T5 architectural-grade aluminum with a tough powder coat finish and reinforced Tig welds to resist cracking, chipping, and bending for a lifetime of performance.
  • Strong Matte White Surface: Features a sophisticated matte white powder coat that is not only elegant but also remarkably resistant to wear, including scratches and corrosion.
  • Clean, Minimalist Installation: Designed for a flawless look with no visible screw holes. Fastening points are discreetly located on the inner border sides. (Note: Fasteners are not included).
  • Custom Airflow Solutions: Pair this diffuser with a customizable plenum box (sold separately) to perfectly match your HVAC system's requirements. Watch our plenums intro video to learn more.
  • Fast Shipping from North America: We ship quickly from Vancouver, Canada. Orders to the USA typically arrive within 2-7 business days after dispatch.
