## Long description

The ERGOVENT RONDO-COANDA-125 is a premium flush-mounted air diffuser engineered for seamless integration into gypsum ceilings. By utilizing the advanced Coanda effect, this unit ensures that air flows smoothly along the ceiling surface, providing efficient and draft-free ventilation for both residential and commercial spaces. Its minimalist, frameless design allows the diffuser to become an invisible part of the interior, as it can be finished with paint or plaster to match the surrounding ceiling surface perfectly.
Advantages
The primary advantage of the ERGOVENT RONDO-COANDA-125 is its ability to blend completely into the ceiling, eliminating the visual clutter of traditional plastic or metal grilles. Because it is constructed from high-quality gypsum, it can be plastered and painted alongside the ceiling, ensuring a monolithic appearance. The Coanda effect technology significantly improves indoor comfort by preventing direct air drafts on occupants, as the air is guided gently across the ceiling before dispersing into the room. This design is highly durable, resistant to temperature fluctuations, and provides a professional, architectural finish to any ventilation system.
Suitable for
Residential living rooms and bedrooms
Modern office spaces requiring aesthetic ventilation
High-end interior design projects
Commercial buildings with suspended gypsum ceilings
This diffuser may not be suitable for installation in environments with high humidity, such as bathrooms or saunas, unless specifically treated with moisture-resistant coatings. It is also not intended for mounting on walls or in exposed ductwork where the flush-mounting capability cannot be utilized.
Key specifications
Material: High-quality gypsum
Diameter: 125 mm
Installation type: Flush-mounted
Design: Frameless, paintable
Air distribution: Coanda effect
To install the ERGOVENT RONDO-COANDA-125, the unit must be integrated into the gypsum board ceiling structure during the installation phase. The diffuser is fixed to the ceiling frame, and the joints are filled with plaster to create a seamless transition between the diffuser and the ceiling surface. Once the plaster is dry, the entire surface can be sanded and painted to achieve a uniform finish. The internal air distribution components are then inserted to complete the setup.
What to consider before purchase
Ensure your ventilation duct diameter matches the 125 mm requirement
Verify that the ceiling construction allows for flush-mounting installation
Plan for professional plastering to achieve the best aesthetic result
Confirm compatibility with your existing ventilation system airflow rates
For optimal performance and a flawless finish, it is recommended to use professional-grade gypsum filler and high-quality interior paint. Ensure the ventilation system is balanced after installation to maintain the intended Coanda effect airflow pattern.
