BUILDMART 36-Inch Linear Slot Diffuser - Double Slot White Aluminum Vent Cover for Ceilings, Walls & Floors

Elevate Your Space with a Modern Linear Slot Diffuser

The BUILDMART 36-inch Linear Slot Diffuser combines industrial strength with architectural finesse. This decorative aluminum vent cover is designed to enhance ceilings, walls, and even floors, delivering a clean, hotel‑style look without compromising airflow. It is a decorative, non-structural cover that works with your existing HVAC system to create a seamless transition between rooms while maintaining a contemporary vibe.

Key specifications include a dual-slot face for a refined linear appearance, a neck that fits into the vent opening, and an airflow profile that supports smooth, even distribution. With a nominal CFM of 302 and an effective velocity near 9.8 ft/s, you can expect a steady, unobtrusive presence that complements modern interiors. The unit is non‑filter by design, meaning you can pair it with your system’s filter configuration as needed.

What sets it apart

• Commercial-grade solid aluminum for lasting durability and a premium look
• Architectural, low-profile design suitable for ceilings, walls, and floors
• Retrofit-ready with a hidden mounting approach to preserve aesthetics
• Can be used as both supply and return vent cover
• Paintable white finish (also available in black) to match decor

Fits a range of spaces

• Bathrooms, kitchens, living rooms, offices, and commercial environments
• Remodels or new construction where a sleek, architectural vent is desired

Important sizing note: measure the interior duct opening (the plenum box) to determine the correct neck size rather than the face size. This model comes in multiple widths and lengths, with 70+ standard vent cover sizes and 40+ linear slot diffuser options available. White and black colors are stocked, and many models are paintable to suit your project.

Installation is designed to preserve aesthetics. Pre‑drilled holes align with the diffuser’s hidden mounting points, allowing you to screw it in without visible front screws. For detailed guidance, reference the included instructional videos.

Care and maintenance

• Wipe with a damp cloth to keep the aluminum finish looking pristine
• Avoid abrasive cleaners that could dull the surface
• Because this is a non-filter model, ensure compatibility with your HVAC setup if a filter is present in the machine

Whether you’re refreshing a space or planning a full redesign, this vent cover offers a refined look with practical performance. It blends architectural form with everyday usability, creating a sense of modern clarity while aligning with current interior trends.
