Advanced ventilation with high efficiency and whisper-quiet operation. For an optimal indoor climate in every home.
Smart design, easy installation
The new Vasco heat recovery ventilation system first filters the incoming outdoor air before passing it through a high-quality heat exchanger. This ensures a healthy and comfortable indoor climate at all times.
The 275/350/425/500 Boost (H) ventilation unit combines ease of use with maximum flexibility: the unit is reversible and equipped with both top and bottom connections, resulting in significantly more installation possibilities.
Thanks to the integrated dual bypass function, the system operates with maximum energy efficiency. Whenever heat recovery offers no added value, the airflow automatically bypasses the heat exchanger. In addition, the free cooling function (ideal during cool summer nights) and free heating function (for example on chilly spring or autumn days) ensure an optimal indoor climate, perfectly adapted to outdoor conditions.
Optional enthalpy heat exchanger
The 275/350/425/500 Boost (H) is also available with an enthalpy heat exchanger (“H” type). This innovative exchanger not only recovers heat and cooling energy, but also moisture from the extract air. As a result, the relative humidity in the home remains better balanced, even during the winter months. All of this is fully integrated into the ventilation unit, without the need for additional components.
CO₂ ZoneControl
CO₂ ZoneControl is an innovative solution for demand-controlled and zoned ventilation. The system operates based on the measured CO₂ levels in specific zones of the home.
By installing two air dampers on separate supply air ducts, the airflow can be individually controlled in two different zones.
EasyFlow®
Together with your Vasco ventilation unit, the Vasco EasyFlow® air duct system creates a unique, whisper-quiet ventilation solution. Thanks to the limited number of components and a smart logistical concept, installation is fast, simple and hassle-free.
The EasyFlow® duct system is also ideally suited for installation in:
· suspended ceilings · (lightweight) screed layers
· insulation layers · cement screeds
