H'Expo 2026: VTI expands its offering for the renovation of collective ventilation systems

VTI will participate in the 2026 edition of the H'Expo trade fair, organized as part of the Hlm Congress at the Bordeaux Exhibition Center. This event brings together more than 10.000 social housing decision-makers each year, including social housing organizations, design offices, architects, manufacturers and service providers.

The French manufacturer will present its latest low and high pressure ventilation solutions as well as its support tools for the energy renovation of multi-unit buildings.

SUPAIR'VENT extends its VTI range to high-pressure mechanical ventilation

Launched in 2025, the SUPAIR'VENT range marks VTI's entry into the high-pressure controlled mechanical ventilation market. It is offered in three versions: self-regulating, humidity-controlled type A, and humidity-controlled type B.

These single-flow CMV units are intended for renovation operations in collective buildings including high-rise buildings, long extraction columns or complex air networks.

The range combines a high-efficiency EC motor with electronic control. The units can be installed on the roof, in the attic, or in a technical room, depending on the chosen configuration. VTI also highlights 360° air discharge, designed to limit the noise level of the unit.

“We are particularly proud to have developed a complete range of high-pressure MVHR systems in record time, a project that mobilized our entire R&D team. These solutions incorporate numerous innovations, such as 360° air discharge, which reduces noise from the unit. They are also demountable and adjustable, providing greater flexibility of use than the competition,” says Sylvain Mondina, Head of Design and R&D at VTI.

More than 50 projects launched in 2026

According to VTI, the first projects integrating SUPAIR'VENT have been carried out in Maubeuge, Paris, Montreuil, Créteil, Montpellier, Le Grand-Quevilly and Strasbourg.

The manufacturer indicates that more than 50 projects utilizing its new high-pressure range were signed in 2026, both in condominiums and in social housing.

VTI also announces that the SUPAIR'VENT and SUPAIR'VENT COMPACT ranges have a Technical Approval issued by the Scientific and Technical Center for Building (CSTB).

A compact version for medium-sized buildings

SUPAIR'VENT COMPACT incorporates the core technology of the range in a more compact format. This version is particularly suited to intermediate buildings of the R+3 to R+5 type, installations with short ductwork, and technical spaces with limited space.

It is also intended for partial renovations and projects with tight budgets. Among the announced features are:

• reduced size and weight;
• a simplified installation without a plenum;
• an architecture optimized to control costs;
• ventilation performance comparable to that of the standard range, according to VTI.

MAXIVENT MV2 EC PLUS C4 for individual ducts

VTI will also present MAXIVENT MV2 EC PLUS C4, a new generation of hybrid air and gas extractor intended for collective buildings undergoing renovation equipped with individual ventilation and smoke evacuation ducts.

The appliance can operate in static mode, using natural draft, or in dynamic mode thanks to its motor. Its C4 rating corresponds to its resistance to a temperature of 400°C for 30 minutes.

The design is based in particular on a protected engine compartment, a dedicated cooling circuit, aerodynamic optimization and an architecture designed to limit heat transfer to the engine.

VTI presents this patent-pending solution as suitable for configurations combining boilers and ventilation on existing individual ducts. However, the claim that it is the only solution of its kind available on the market is based solely on the manufacturer's statements.

MyVTI 3 automates project sizing

The new version of the MyVTI configurator should allow design offices, architects and project owners to prepare their low or high pressure ventilation projects online.

The tool guides prescribers through several steps:

• choice of system and building typology;
• housing settings;
• 2D drawing of the rooftop network;
• calculation of pressure and flow rate;
• automatic sizing of the installation;
• simulation of budget and energy performance.

After configuration, the user can generate the technical documents required for consultation or tendering, including the technical specifications (CCTP), the quote, the CE sheets and the instructions.

Projects and associated documents are stored in a personalized user space so that they can be viewed and updated later.
