Ergovent drop-in frameless louvre 500 mm with connection diameter 75 mm - standard

Ergovent plasterable frameless linear grille 500 mm with 75 mm connection diameter - standard

The Ergovent plasterable frameless linear grille of 500 mm is a linear ventilation grille, specially designed for installation in plasterboard ceilings and walls. The Lineo Single creates a minimalist, subtle slit 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 mm.

Installation of the ventilation grille

The Lineo Single 500 is fixed directly to the concrete ceiling or wooden frame before the plaster frame is installed. 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 plastered. After surface treatment, attaching the grille and connecting the duct system, the entire assembly is finished and painted in the same colour as the ceiling for a sleek, seamless appearance. The Lineo Single has a fixed length of 500 mm, is suitable for a single air supply or exhaust from the ventilation system and is not connectable.

Standard or profile?

• Lineo Single (standard): Separate model for a single, independent connection to a flexible ventilation duct, which must be mounted directly on the concrete ceiling before the plaster ceiling is installed.
• Lineo Profile (profile): Separate model for a single, independent connection to a flexible ventilation duct, which can be placed directly on the plaster frame for faster installation.

Operation

The Lineo Single comes standard with an integrated air control damper at the rear. This can be easily adjusted after installation using an Allen key, allowing the air volume per room to be precisely regulated — without the need for separate valves. The damper is suitable for both air supply and exhaust, making the grille suitable for mechanical ventilation systems.
