Overview
The Ergovent is ideal for modern buildings seeking a minimalist, pleasing to the eye look as it has no visible edges due to being integrated into the ceiling as part of the building process. No other air valve has such a profile. Growing in popularity for high end hotels, modern office buildings and stylish homes.
The Ergovent is made of high-quality gypsum (plaster) allowing the Air Valve to be seamlessly integrated into the drywall ceiling and painted the same colour as the ceiling, so only an aesthetic ring-shaped slot for the air flow remains visible.
Each diffuser comes with a convenient, easy to use ERGOVENT balancing valve. If there is a need to additionally regulate the air flow, we recommend using these dampers for maximum efficiency.

Invisible, Flush-Fit Air Vent for Modern Architectural Interiors
The Rondo Valve by Ergovent is a premium recessed ceiling air valve designed for contemporary interiors where clean lines and minimalist aesthetics are essential.

What Makes the Rondo Valve Different?
Traditional ceiling air valves and diffusers remain visible after installation, often disrupting the clean aesthetic of modern interiors. The Ergovent Rondo valve is designed to be integrated into the ceiling during the building process.
Manufactured from high-quality gypsum (plaster), it becomes part of the ceiling structure itself. Once installed and painted, only a refined circular airflow slot remains visible, creating an invisible ventilation solution that complements minimalist architecture.
No other ceiling air valve offers this level of flush integration.
Ideal for Modern & High-End Projects
The Rondo plaster-in air valve is commonly used in:
-
Luxury homes and new builds
-
Architect-designed properties
-
High-end apartments
-
Boutique hotels
-
Contemporary office developments
-
Interior-led commercial spaces
It is particularly popular in projects where exposed grilles or vents would compromise design intent.
Quiet & Efficient Airflow Performance
Each unit includes an ERGOVENT balancing valve, allowing installers to regulate airflow effectively. For projects requiring additional control, compatible dampers can be used to fine-tune air distribution and maximise ventilation efficiency.
The design supports smooth, quiet airflow, making it suitable for bedrooms, living spaces, offices and hospitality environments.
Available Sizes
The Rondo Valve is available in the following duct connection diameters:
-
100mm
-
125mm
-
150mm
-
160mm
This ensures compatibility with standard circular and spiral ducting systems.
Installation Considerations
The Ergovent Rondo valve must be installed during the ceiling construction phase, as it is plastered directly into drywall. It is not a retrofit solution and should be specified at design stage.
For connection to circular ductwork, ensure correct sizing and sealing for optimal airflow performance.
Also Available: Square Model (KVADRO)
Prefer a square design? The Ergovent KVADRO model offers the same flush, plaster-in integration in a modern square format. See related products for details.
