Linear Slot Return
Complete your linear slot system with the Linus ProAir Linear Slot Return—a fully extruded aluminum return air grille engineered to match the clean, modern aesthetic of your supply diffuser installation. Whether you're specifying for a hospital, hotel, office buildout, or high-end residential renovation, the Linear Slot Return delivers a seamless, architectural finish without compromising on durability or performance. One system. One look. Zero visual compromise.
Available in 1 to 4-slot configurations with 1/2", 3/4", and 1" slot widths. Standard and custom sizes available in any length.
100% Extruded Aluminum Construction No steel, no plastic, no stamping, no casting. Pure North American-made extruded aluminum resists rust, corrosion, and moisture—critical for the humidity and airflow demands of any HVAC system. At approximately 15% heavier than standard market alternatives, you can feel the quality difference the moment you handle it.
1 to 4-Slot Configurations Choose the slot count that suits your return air volume and aesthetic requirements. Available with 1/2", 3/4", and 1" slot widths to match your supply diffuser specification and maintain a consistent look throughout the space.
Continuous Run Capability Available in any length. Units over 84" are joined using alignment pins for a seamless, uninterrupted appearance—ideal for long open-ceiling runs in commercial and high-end residential spaces.
Optional Pattern Controllers for Supply Applications Need flexibility in your specification? Add pattern controllers to convert the unit to a supply diffuser application. One product that works both ways, keeping your procurement simple and your ceiling clean.
Field Cuttable Ordered to length from the factory and cuttable on-site using a fine tooth, high speed carbon blade. A maximum of 3" can be trimmed from each end—giving installers the flexibility they need during fit-out. Remove end caps before cutting and reattach once complete.
Multiple Mounting Options Four installation configurations to suit any project requirement: standard screw holes, concealed bracket (+10%), lay-in with no mounting hardware, or fully concealed screw holes. Every option delivers a clean finish appropriate for commercial and architectural applications.
Concealed Fastener Design No visible hardware on the face of the unit. Screws are fully hidden, delivering the seamless architectural finish that specifiers and designers demand in ceiling and wall installations.
Faceplate Profile: 0.055" A slim, low-profile faceplate that sits flush and clean against any ceiling or wall surface—purpose-built for modern interiors where every detail matters.
White Powder Coat Finish (Standard) Clean, professional, and consistent. All Linear Slot Returns ship in a durable white powder coat finish. Custom colors, sizes, and mud-in options are available—contact the sales team to discuss your project requirements.
