Ergovent plasterable frameless louvre 1050 mm with connection diameter 75 mm - modular - 2 slots

Ergovent flush-mount frameless linear grille 1050 mm with 75 mm connection diameter - modular - 2 slots

The Ergovent flush-mount frameless linear grille of 1050 mm is a linear ventilation grille specifically designed for installation in plasterboard ceilings and walls. The Lineo Pro Puzzle creates minimalist, subtle slots in the surface, making it barely noticeable and seamlessly blending into the interior design. The ventilation grille is designed for flexible plastic duct systems with a connection diameter of 75 or 90 mm.

Installation of the ventilation grille

The Lineo Pro Puzzle is mounted on plasterboard profiles and can be linked to form longer, continuous ventilation slots. The puzzle system snaps the segments effortlessly together, ensuring a tight, invisible joint. For proper adhesion, it is important to first clean the surface and any joints from dust. To prevent cracking in the finish, it is recommended to apply a thin layer of glass fibre mesh over the visible surface of the grille. After this, a primer can be applied to the areas that will be skimmed. Once the surface treatment, grille mounting and duct connection are complete, the entire assembly is finished and painted in the same colour as the ceiling for a clean, seamless appearance. The Lineo Pro Puzzle has a fixed length of 1050 mm and can be extended by connecting multiple Lineo Pro Puzzle grilles, connectors, or corner pieces. Duct connections or covers are attached at a 45-degree angle on the back side.

Standard, profile or modular?

• Lineo Pro Single (standard): Standalone model for a single, independent connection to a flexible ventilation duct, which must be installed directly on the concrete ceiling before mounting the plaster ceiling.
• Lineo Pro Profile (profile): Standalone model for a single, independent connection to a flexible ventilation duct, which can be mounted directly on the plaster frame for faster installation.
• Lineo Pro Puzzle (modular): Modular model for connection with other flush-mount linear grilles, connectors, or corner pieces, which can be mounted directly on the plaster frame for faster installation.

Operation

The Lineo Pro Puzzle standardly includes an integrated airflow damper on the rear. After installation, it can be easily adjusted with an Allen key, allowing precise regulation of air volume per room — without the need for separate valves. The damper is suitable for both supply and extract air, making the grille appropriate for mechanical ventilation systems.
