New Round Diffuser Expands the Slot Tile Line with a Refined Solution for High-Airflow Commercial Ceiling Applications
Invi Air, a leading manufacturer of HVAC diffusers and frameless vent covers, is pleased to introduce the Slot Tile Round Diffuser, a new circular addition to its Slot Tile product line designed to deliver high airflow performance while maintaining a clean, integrated ceiling appearance.
Designed for acoustical and tile grid ceilings, the Slot Tile Round Diffuser fits standard 24-inch x 24-inch T-bar and drop ceiling grids, blending directly into the ceiling tile for a nearly invisible finish. Available as a kit with the plenum box, the diffuser is suitable for both supply and return applications and delivers a flush condition that aligns with the depth of surrounding ceiling tiles. This allows lighting, materiality, and architectural detailing to remain the focus across offices, healthcare environments, hospitality settings, educational spaces, and other commercial interiors.
The new Slot Tile Round Diffuser joins Invi Air’s Tile Diffuser collection as the second product in the line, following the Slot Tile Square Diffuser launched in 2025. Both formats are crafted from Invi Air’s proprietary composite diffuser material, engineered as a high-performance alternative to traditional metal diffusers. Compared to metal, the material helps reduce condensation by up to 95% and noise by up to 50%, while also helping to minimize static and dust buildup. These benefits support occupant comfort, cleaner ceiling conditions, and a more discreet visual presence overhead.
The round profile expands the design possibilities of the Slot Tile line, particularly for projects where softer geometries, circular lighting, or more sculptural ceiling layouts are part of the concept. Invi Air can also customize the diffuser by retrofitting existing duct openings or correctly sizing the product to meet specific airflow needs, making it a practical solution for both new construction and retrofit applications.
The diffuser is easy to paint, allowing it to match virtually any ceiling color or texture and blend seamlessly with the surrounding architecture. Its design also supports quick, simple installation, helping contractors achieve a polished result without a complicated process.
From a long-term design value perspective, the product’s strength lies in its durable, high-performance material construction and ability to support evolving interiors. Its proprietary composite material has a zero carbon emissions footprint and the product is ASTM E84 Class A rated and CARB Phase II compliant, offering a specification option that balances design integration, performance, and lasting value.
