Ergovent Insertable Frameless Round Ventilation Valve, 125 mm - with Coanda effect

Ergovent Flush-Mount Frameless Round Ventilation Valve 125 mm – with Coanda Effect

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

Advantages and Features

• Frameless and flush-mount design: The ventilation valve must be fully plastered for a seamless finish. The visible surface is paintable and integrates with the plasterwork, making it ideal for modern interiors.
• Coanda effect: The supply air adheres to the ceiling surface and spreads evenly throughout the room. This prevents drafts, even when standing directly beneath the valve.
• Universal connection options: The valve is very easy to connect to metal or flexible ventilation ducts with a diameter of 125 mm. Additionally, it can be connected via a connection box to plastic duct systems, making it suitable for various applications.
• Includes control damper: The supplied control damper allows precise adjustment of the airflow to the desired capacity for each room.
• Solid gypsum housing: The high-quality, bubble-free cast structure ensures a smooth finish that is easy to paint over.
• Additional edge protection: An internal plastic shield prevents damage to the edges of the plaster finish during removal or incidental impact.

Installation and Applications

The ventilation valve must be connected to the desired ventilation duct before plastering, with a minimum installation depth of approximately 140 mm. The valve is then plastered in and can be painted in the same colour as the ceiling. The integrated fixing elements provide stable anchoring. After finishing and painting, the valve forms a seamless unit with the surface. The adjustable air regulator remains accessible for commissioning simply by removing the cover. Thanks to its timeless, minimalist design, this valve is suitable for use in residential homes, apartments, offices, and other spaces where aesthetics and comfort go hand in hand.

Air Distribution and Comfort Experience

The Ergovent Rondo Coanda has been developed for both supply and exhaust air. Due to the Coanda effect, the air is guided with controlled diffusion along the ceiling, which is especially noticeable in spaces where people are directly beneath the valve. This ensures air distribution remains comfortable and virtually imperceptible.
