Seamless Air Distribution

LINEO PRO diffusers combine advanced airflow control with installation flexibility and a seamless architectural finish. Built-in balancing dampers allow airflow adjustment after installation, while modular connection options simplify duct routing and assembly. Once plastered and painted, only a clean linear slot remains visible, blending naturally into modern ceiling and wall designs.

Use Cases

Built for larger residential and commercial spaces, this dual-slot profile delivers increased airflow capacity while maintaining the same hidden architectural finish and clean ceiling lines.

Designed for living rooms, bedrooms, and hospitality spaces requiring discreet air distribution. The modular puzzle-lock design allows longer continuous runs while maintaining a clean, frameless appearance throughout the ceiling.

Ideal for kitchens, hallways, and areas with built-in cabinetry, this profile integrates into the gypsum ceiling plane. It disappears after the final painting, leaving nothing behind but a precise linear slot.
