Product Overview
The ERGOVENT RONDO Coanda 125mm is a premium flush-mounted round air valve designed for discreet ventilation in modern homes, apartments and commercial interiors. Installed into plasterboard ceilings or walls, the RONDO diffuser creates a clean, minimal finish with only the subtle circular airflow slot visible after plastering and painting.
This Coanda Effect version is designed to direct supply air along the ceiling surface rather than straight down into the room. This helps support more even air distribution and can reduce the feeling of draughts, making it ideal for comfort-focused ventilation projects.
Suitable for use with MVHR, MEV and other ducted ventilation systems, the RONDO Coanda 125mm diffuser offers both performance and a high-end interior finish. Supplied with a damper, it allows airflow to be adjusted during commissioning to help achieve the required balance for the room.
