Coanda Effect
Ventmann’s PCircle Coanda delivers exceptional comfort through precise airflow, combining sustainability, performance, and design. Its unique form resolves the challenge of achieving the Coanda effect in supply air diffusers while meeting architects’ and designers’ aesthetic demands.
HOW COANDA EFFECT WORKS
INNOVATIVE CIRCULAR DESIGN
The PCIRCLE diffuser cap is equipped with our advanced Click system, designed for fast, precise, and hassle-free installation. This upgraded mechanism not only streamlines setup but also delivers environmental advantages and performs reliably across a broader temperature range than the older magnetic system. As the most adaptable unit in our collection, the PCIRCLE integrates effortlessly into a wide variety of interiors while ensuring superior air distribution. Like all frameless diffusers in our portfolio, it supports both air supply and extraction, enabling multiple installations in the same space without compromising on visual harmony.
Staying true to our sustainability values, the PCIRCLE Coanda is crafted from a proprietary gypsum-composite material. This eco-conscious choice significantly reduces embodied carbon compared to conventional aluminum or plastic options. The gypsum build also makes it plaster-and-paint friendly, blending seamlessly with surrounding surfaces. When paired with the frameless mounting system, the result is a discreet, near-invisible installation that delivers uncompromising performance.
To accommodate different project requirements, all standard PCIRCLE models are fully customizable:
– smallest standard diameters
– medium diameter option
– airflow up to 200 m³/h
– for increased air capacity
– largest standard diameter
– airflow up to 300 m³/h
– for maximum air delivery needs
