ERGOVENT RONDO COANDA
Round Frameless Gypsum Diffuser


RONDO COANDA 100 / 125
The ERGOVENT RONDO COANDA 100/125 is a recessed round gypsum diffuser for drywall ceilings and walls. The body is plastered and painted to match the surrounding surface, leaving no visible frame or trim ring. Air leaves the gap sideways and travels along the surface rather than dropping straight down, which suits positions where people sit or work directly beneath the diffuser.
