    V4A² Premium

    ACOUSTIC WHOLE-HOUSE FAN – 5 ROOMS

    Silent operation and efficient ventilation of the whole dwelling

    The V4A²’s EC-Motor (Electronic Commutation Motor) adjusts its speed/torque using an electronic card. This feature helps maintain the required pressure, ensuring that airflow matches the requirements of the connected demand-controlled exhaust units. This keeps power consumption and noise emissions to a minimum.

    New and improved SFPs as low as 0.16W/l/s for both rigid and semi-rigid duct resulting in better DEAP and SAP results. Listed on the PCDB Appendix Q.

    An efficient motor

    The V4A²’s EC-Motor (Electronic Commutation Motor) adjusts its speed/torque using an electronic card. This feature helps maintain the required pressure, ensuring that airflow matches the requirements of the connected demand-controlled exhaust units. This keeps power consumption and noise emissions to a minimum.

    Optimised for silence

    The high efficiency EC-Motor is mounted on flexible links and is encased in a double-skin envelope: V4A² is optimised to work silently.

    User-friendly maintenance

    Maintenance is simple because the fan is inside the dwelling: the cover is simply lifted off and the impeller is easy to clean. The electrical part is removable, so the components can be replaced without removing the impeller from its support or replacing the entire fan. 

    An eco-design ventilation system 

    Made from recycled plastics, the new V4A² is part of an eco-design approach. With its potentiometer system enabling the product’s performance to be adjusted to suit the needs of the home, this ventilation unit saves energy and reduces its impact during use.
