Our "performance" range features a specific airflow that offers exceptional comfort. It also provides the sustainability, performance, and aesthetic versatility that are hallmarks of every Ventmann product. The PCircle Coanda’s design solves a specific challenge where the physics of creating air diffusers that produce a Coanda effect were at odds with the aesthetic requirements of designers and architects. This challenge has proved particularly difficult to solve in air diffusers that supply air, as opposed to those that simply extract it.

Modern buildings require high quality air supply and extraction. Occupants don’t expect to feel strong jets of air or currents, but a high amount of air still needs to be circulated according to modern building standards. Standard diffusers blow out air in spikes, with the airflow forming a shape like that of a torch light.
