Ergovent drop-in frameless louvre 1000 mm with connection diameter 90 mm - standard

Ergovent Recessed Frameless Linear Grille 1000 mm with 90 mm Connection Diameter - Standard

The Ergovent recessed frameless linear grille of 1000 mm is a linear ventilation grille, specifically designed for installation in plasterboard ceilings and walls. The Lineo Pro Single creates a minimalist, subtle slot 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 Single is fixed directly to the concrete ceiling before mounting the plaster frame. 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. Afterwards, a primer can be applied to the areas that will be skimmed. After surface treatment, fixing the grille, and connecting the duct system, the entire assembly is finished and painted the same colour as the ceiling for a clean, seamless appearance. The Lineo Pro Single has a fixed length of 1000 mm, is suitable for a single air supply or extract connection from the ventilation system, and is not connectable. Duct connections or covers are fitted at a 45-degree angle on the rear side.

Operation

The damper is suitable for both air supply and extract, making the grille suitable for mechanical ventilation systems.
