RONDO / KVADRO · Round & square point diffusers
Round concealed point diffuser — a discreet circle of air, flush with the surface and painted to match.
RONDO is the round point diffuser of the ERGOVENT range. It mounts flush into the ceiling or wall, takes the same paint as the surrounding surface and provides quiet supply or extract air for individual rooms — bedrooms, bathrooms, dressing rooms and other spaces where the ceiling should stay calm and uninterrupted.
Living areas and suites where the ceiling stays perfectly calm.
Compact premium interiors where every surface is part of the design.
One consistent ceiling detail from mock-up room to handover.
Workspaces with clean, deliberately drawn ceiling plans.
Quiet rooms where nothing should draw the eye upward.
High-end renovations replacing visible grilles with clean planes.
Discreet point ventilation for individual rooms.
The device disappears — what remains is a slim slot or a discreet opening in the surface.
The body sits inside the build-up and the flange is plastered level with the ceiling or wall.
Painted together with the surface — same paint, same colour, same sheen.
Planes stay continuous, and ventilation aligns with lighting and joinery instead of fighting them.
