Fresh Air Supplies Highlights Rising Demand for Invisible Ventilation as RONDO Air Valves Gain UK Traction
Fresh Air Supplies is reporting increased demand from architects, contractors, and interior designers for discreet, design-led ventilation solutions, with the Ergovent RONDO air valve emerging as a preferred option for modern residential and commercial projects.
Discrete Design for Contemporary Interiors

The Ergovent RONDO is engineered to sit flush with the ceiling surface, offering a seamless, minimalist finish compared with traditional protruding ventilation valves. Its interchangeable covers and precision airflow design support both aesthetic and functional requirements across new builds, refurbishments, and retrofit installations.
Performance and Engineering Quality
Manufactured to exacting European standards, the RONDO diffuser provides balanced airflow, low acoustic output, and long-term durability. It is suitable for both supply and extract systems and performs best when paired with high-quality ductwork and airtight fittings.
Installation Efficiency
The RONDO’s mounting system allows contractors to achieve a clean, level installation quickly. Key installation practices include correct planning of ducting routes, secure airtight connections, and simple post-installation airflow adjustments.
A Cleaner Alternative to Traditional Valves
Conventional ceiling valves often disrupt clean ceiling lines and create uneven airflow. The RONDO offers a flush, unobtrusive appearance, uniform air distribution, and straightforward cleaning due to its removable front section.
