Ergovent Recessed Frameless Round Ventilation Valve 125 mm - with Coanda Effect

The Ergovent recessed frameless round ventilation valve 125 mm with Coanda effect is designed for applications where you want to combine ventilation with a sleek and discreet ceiling or wall appearance. This built-in valve is fully integrated into the plasterwork, leaving only a subtle round opening visible. Thanks to the Coanda effect, the air is spread horizontally along the ceiling instead of being blown directly downward. This creates a comfortable indoor climate without noticeable drafts, even when standing directly beneath the valve.

Benefits and Features

• Frameless, recessed design: The ventilation valve must be fully plastered for a seamless finish. The visible surface is paintable and blends with the plasterwork, making it ideal for modern interiors.
• Coanda Effect: The supply air adheres to the ceiling surface and disperses evenly throughout the room, preventing drafts even directly under the valve.
• Universal connection options: The valve is easily connectable to metal or flexible ventilation ducts with a diameter of 125 mm. Additionally, it can be connected to plastic duct systems via a junction box, making it suitable for various applications.
• Includes control damper: The supplied damper allows precise adjustment of the airflow to match the required capacity per space.
• Solid gypsum housing: The high-quality, air bubble-free cast structure ensures a smooth finish that is easily paintable.
• Extra edge protection: An internal plastic shield prevents damage to the gypsum finish edges during removal or accidental impact.

Installation and Applications

The ventilation valve must be connected to the desired ventilation duct prior to plastering, with a minimum installation depth of approximately 140 mm. The valve is then recessed with plaster and can be painted to match the ceiling colour. The integrated fastening elements ensure a stable anchorage. After finishing and painting, the valve forms a seamless part of the surface. The adjustable airflow controller remains accessible for balancing by simply removing the cover. Thanks to its timeless, minimalist design, this valve is suitable for residences, apartments, offices, and other spaces where aesthetics and comfort go hand in hand.

Air Distribution and Comfort

The Ergovent Rondo Coanda is designed for both supply and extraction of air. By utilising the Coanda effect, the air is guided along the ceiling with controlled dispersion, which is especially noticeable in spaces where people are positioned directly beneath the valve. This ensures comfortable and virtually imperceptible air distribution.
