At Ventmann USA, our Performance Range is engineered to deliver a precise airflow that ensures maximum comfort while upholding the principles of sustainability, efficiency, and aesthetic flexibility — the foundation of every Ventmann solution.

The PCircle Coanda diffuser was developed to address a long-standing challenge: creating a diffuser that generates a true Coanda effect without compromising the clean, modern look demanded by architects and designers. This is especially complex for supply-air diffusers, where airflow must be both powerful and discreet, unlike extraction systems.

In today’s buildings, high-quality air distribution is essential. Occupants expect fresh, healthy air circulation without the discomfort of noticeable drafts. While standard diffusers often push air in concentrated “spikes,” forming torch-like patterns, Ventmann diffusers disperse air smoothly and evenly — achieving comfort, compliance, and elegance in one design.
