Ergovent Insertable Frameless Round Ventilation Valve, 100 mm - with Coanda Effect

Ergovent Flush-Mount Frameless Round 100 mm Ventilation Valve – with Coanda Effect

The Ergovent flush-mount frameless round 100 mm ventilation valve with Coanda effect is designed for situations where you want to combine ventilation with a sleek and unobtrusive 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 distributed horizontally along the ceiling instead of being blown directly downward. This creates a comfortable indoor climate without noticeable drafts, even when standing directly underneath the valve.

Advantages and Features

• Frameless and flush-mount design: The ventilation valve must be fully embedded in plaster for a seamless finish. The visible surface is paintable and aligns perfectly with the plasterwork, making it ideal for contemporary interiors.
• Coanda effect: The supply air adheres to the ceiling surface and spreads evenly throughout the space. This prevents draughts, even when you are positioned directly under the valve.
• Universal connection options: The valve is easy to connect to metal or flexible ventilation ducts with a diameter of 100 mm. Additionally, it can be connected to plastic duct systems via a connection box, making it versatile for various applications.
• Includes control damper: The supplied control damper allows precise adjustment of the air volume to the desired capacity per room.
• Solid gypsum housing: The high-quality, air-bubble-free cast structure provides a smooth finish that is easily paintable.
• Extra edge protection: An internal plastic shield prevents edge damage to the gypsum 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. Afterwards, the valve is embedded in plaster and can be painted in the same colour as the ceiling. The integrated fastening elements ensure stable anchoring. After finishing and painting, the valve forms a seamless part of 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 homes, apartments, offices, and other spaces where aesthetics and comfort go hand in hand.

Air Distribution and Comfort Experience

The Ergovent Rondo Coanda is developed for both supply and exhaust air. Through the Coanda effect, the air is guided with controlled distribution along the ceiling, which is especially noticeable in areas where people are directly beneath the valve. As a result, airflow remains comfortable and virtually imperceptible.
