The 20-inch linear slot diffuser delivers superior airflow with its sleek white finish and architectural-grade aluminum construction. Featuring dual 25mm slots with 180° adjustable blades, it provides 17% greater airflow than our standard two-slot 19mm models while reducing static pressure by 33%—optimizing HVAC efficiency without straining ductwork. Verified lab results confirm its performance for flow rate, noise levels, and pressure in the performance section. See our smoke test video to observe the precise air distribution in action. Professional installation recommended for optimal results.
- Clean, Modern Design: With a 20" x 3½" nominal size, this linear slot diffuser is engineered with two sharp, 1-inch openings for a minimalist look that complements any commercial or residential space. (Please see the diagram for precise measurements).
- High-Velocity Airflow Performance: The wider 1-inch slot is a major upgrade from standard 19mm vent covers, enabling a significantly higher volume of air to move through quietly and efficiently for demanding HVAC systems.
- Eliminates Ceiling Dust Marks: An integrated gasket creates a perfect seal against the ceiling tile, preventing leaked air from causing unsightly smudges and ensuring all conditioned air is delivered into the room.
- Rugged Commercial Construction: Built from heavy-gauge 6063-T5 aluminum and fortified with robust Tig welds to withstand the rigors of daily use in any environment.
- Strong Matte White Surface: Features a sophisticated matte white powder coat that is not only elegant but also remarkably resistant to wear, including scratches, corrosion, and fading.
- Seamless No-Screw Aesthetic: Achieve a flawless, uninterrupted look with a design that hides all mounting hardware on the interior edges for a clean install. (Note: Fasteners are not included).
- Optimize Your Air Distribution: For peak HVAC efficiency, pair this air diffuser with an custom plenum box (sold separately) to perfectly balance airflow. Check out our video to learn more.
- Fast North American Shipping: We dispatch promptly from our warehouse in Vancouver, Canada. Delivery to most US locations is completed within 2-7 business days.

Linear Slot Diffusers: The Smart Choice for Modern HVAC Systems
Why 6063-T5 Aluminum is the Gold Standard for Your Linear Slot Diffuser
CFD Airflow Analysis Services for Smarter HVAC Design
The Engineer's Standard for Commercial HVAC Grilles and Diffusers
In professional HVAC design, "commercial grade" is a promise of performance, backed by data. It provides the detailed technical information—from the composition to certified metrics on NC (noise criteria), flow rates, and pressure drop—that engineers rely on for precise specification and predictable results.
We uphold this promise by subjecting our products to testing aligned with ASHRAE Standard 70-2006 and ADC1062:GRD-84. Our design philosophy leverages computational fluid dynamics (CFD) to continuously innovate, creating energy-efficient solutions that meet the highest standards of modern building design.
For over two decades, since 1997, we have specialized in manufacturing high-performance linear slot diffusers (1-12 slots) for commercial applications. Contact our product specialists at +1-604-437-1527 for expert consultation on your next project.
