Disappair: the invisible CMV that combines design and comfort in the most delicate projects
Disappair is the invisible VMC system from VMC Italia: without visible grilles, it guarantees comfort, efficiency and design in perfect harmony with the architecture

Ensuring indoor air quality is a priority in modern projects, but it's not always easy to do so without compromising the aesthetic balance of the spaces. When working on historic buildings, protected architecture, or carefully designed spaces, even a simple technical element can become an obstacle. This is where Disappair comes in, the controlled mechanical ventilation system designed by VMC Italia , capable of providing efficient and silent air exchange without anyone noticing.
Disappair is a concealed VMC system that uses completely invisible supply and return vents that integrate seamlessly into walls, ceilings, or floors. Instead of traditional grilles, airflow occurs through micro-holes hidden behind standard 503 plates, the same ones used for switches and electrical outlets. The result? A seamless, elegant line, where technology disappears to make room for the architectural design.
How the Disappair system works: efficiency, silence and design freedom
The heart of the system is the special Disapp503 vents, designed to ensure optimal air diffusion with a flow rate of up to 30 m³/h and a noise level of less than 25 dB(A), making them virtually inaudible. These terminals can be installed in traditional flush-mounted boxes, allowing for seamless integration with any home or professional style.
The air is distributed through a system of antibacterial and antistatic flexible pipes, called Disapptube, which connects the diffusers to the silenced plenum, reducing turbulence and pressure drops. Completing the system is the GAM 15 or 22 VMC unit with a high-efficiency heat recovery unit (>90%) and low-consumption EC fans, which can be positioned in the utility room or recessed into the wall.
The system's modularity allows for customized designs for any environment, adapting to both small apartments and entire buildings. Disappair can be configured both centrally and in combination with decentralized systems, with the option of integrating Wi-Fi home automation controls and smart settings for flow rate optimization, maintenance, and energy savings.
Ideal solution for protected projects, historic buildings and prestigious architecture
One of Disappair 's main strengths is its ability to disappear into its surroundings. No exposed grille, no aesthetic compromises . For this reason, it is particularly suitable for redevelopment projects in historic city centers, where architectural and landscape constraints require non-invasive solutions. But it is also ideal for museums, charming hotels, showrooms, luxury homes, and any other environment where every detail counts.
From a technical standpoint, the system fully complies with European and national regulatory requirements regarding energy efficiency, sustainability, and indoor comfort. Air quality is guaranteed by ePM1 70% (F7) filters , with the option of adding electrostatic filters and ionization systems for further reduction of fine dust, VOCs, and pathogens.
Silence is also crucial: with levels below 25 dB(A), the system falls squarely within the acoustic comfort classes required for high-end homes. And maintenance? Quick and easy: the filters are accessible from the front, the vents can be cleaned with a simple cloth, and the internal surfaces of the ducts are designed to reduce dust accumulation.
