EvoAir A250S G2 is a Eurovent-certified heat-recovery ventilation unit that combines high capacity with energy-efficient operation and thoughtful industrial design. The unit has been developed using experience from Nordic climate conditions and is designed for reliable, energy-efficient operation all year round. EvoAir A250S G2 is manufactured in Älvsbyn and builds on many years of experience in ventilation solutions. The unit has a third-party verified Environmental Product Declaration (EPD). The unit is well suited to residential ventilation and smaller premises such as offices, preschools and workshops.
The unit is equipped with a rotary heat exchanger with temperature efficiency of up to 89% for effective heat recovery. Energy-efficient EC fans also contribute to low energy consumption and stable operation. Eurovent certification means that the stated performance data are verified in accordance with established European standards.

EvoAir A250S G2 is intended for installation, for example, in an attic, storage room or other technical space. The unit is supplied complete with user-friendly controls and a separate 4.3-inch touch display as standard. This provides a complete control and operating solution from the outset, with no need to add a separate display. The post-heating coil and sensors are integrated into the unit to simplify installation and commissioning. The unit is ready for operation with connection via a cable with plug or connector.
EvoControl Touch

Control is via the supplied 4,3-inch colour touchscreen, which provides a clear and intuitive overview of the unit's functions and operation. The system has a wired network connection for stable communication, and the EvoCloud cloud service is included as standard. EvoCloud allows the unit to be managed and monitored remotely from a phone, tablet or computer. This makes it easy to adapt operation to your needs, review measurements and history, and keep a clear overview of current operating status.
For integration with other control and building-management systems, Modbus TCP is also supported, making connection to a supervisory control system easier.
