VOLT'AIR ÉVOLUTION® — A breath of fresh air, a gain in energy! The only truly patented Low Pressure Mechanical Ventilation solution on the market.
Designed and manufactured in France by VTI, VOLT'AIR ÉVOLUTION® is the first and only low-pressure mechanical ventilation solution using sweeping technology truly suited to the renovation of residential buildings constructed before 1982.
Thanks to its patented fan and its box specifically developed to operate at very low vacuum (<35 Pa), VOLT'AIR ÉVOLUTION® efficiently uses existing natural ventilation ducts — where a conventional CMV would be ineffective.
A technological innovation from French R&D
The VTR EVO ventilation units, the heart of the system, were entirely designed in VTI's R&D cell.
➡️ Patented fan, developed specifically for low pressure.
➡️ Yields up to 46%, double the regulatory requirement.
➡️ Lowest power consumption on the market, with self-regulated speed (VAR) operation that continuously adjusts fan rotation according to the building's actual needs.
A system designed for responsible renovation
- Reuse of existing conduits, without heavy work.
- Eligible for Promotelec, CERQUAL, BBC and ErP Ready labels.
- Infobox Revolution, our connected ventilation solution: real-time monitoring, remote configuration, alarm and alert reporting.
- 100% French manufacturing, in our factories, guaranteeing quality, responsiveness and durability of components.
A measurable impact on air quality and energy performance
Tests conducted by the CSTB demonstrate:
✅ Maintaining CO₂ levels below 1,000 ppm, ensuring comfort and concentration.
✅ Relative humidity regulated between 40 and 75%, ideal comfort range for health.
✅ An average consumption of €2,3/year/housing, i.e. a minimal energy footprint.
VOLT'AIR ÉVOLUTION® — Responsible and connected ventilation
A solution that combines technological innovation, energy efficiency, and the reuse of existing infrastructure. A forward-looking choice for the sustainable renovation of France's housing stock.
The VOLT'AIR ÉVOLUTION ventilation solution has been specially designed for the rehabilitation of collective residential buildings (social housing, condominiums), integrating natural ventilation ducts (Shunt, individual or Alsace type ducts), built before 1982.
