Gypsum diffusers

The most versatile and popular unit, the Performance Circle model, is a frameless diffuser suitable for virtually any room or interior design style. It was nominated with a prestigious Red Dot Design Award 2023. The product features a specific airflow that offers exceptional comfort, along with the sustainability, performance and aesthetic versatility that are hallmarks of every Ventmann product. The Circle Coanda’s design solves a specific challenge where the physics of creating air diffusers that create a "coanda effect" were at odds with the aesthetic requirements of designers and architects.

PCIRCLE

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 air flow forming a shape like that of a torch light.‎ But air diffusers that create a "coanda effect" can supply a very high volume of air without users feeling it.‎ The "coanda effect" is when a jet of air or fluid wraps around and then follows the contours of a convex surface.‎ In air diffusers, the effect is that the air flow spreads parallel to the ceiling rather than downwards in jets.‎ This means if you are standing directly underneath the diffuser, you still won’t feel the direct jet of air — this makes it much more comfortable for users.‎

All Pcircle standard models can be adapted to the needs:

The diffuser cap is supported by the new Click system.‎‎ This system makes it even easier to put the cap in place correctly.‎‎ It is also more environmentally friendly and has a higher operational temperature range than the magnets previously used.‎‎ This is the most versatile unit.‎‎ It fits the design of most rooms and provides comfortable air flow in majority of situations.‎‎ Pcircle, like all other frameless diffusers, can be used for both air supply and air extraction.‎‎ Multiple beautiful, sleek Pcircle diffusers can be installed in a single room.‎‎

100mm or 125mm these are the smallest standard connection nozzle diameters‎‎

Like all Ventmann products, the PCIRCLE Coanda is environmentally friendly, thanks to Ventmann’s use of a unique gypsum-composite.‎ These diffusers have significantly lower embodied carbon than their aluminium or plastic counterparts.‎ Gypsum also has the advantage that it can be plastered and painted over, enabling maximum discretion when the diffusers are installed.‎ This is further enhanced by the frameless mount.‎
