Flow400-R
New Flow400-R is the ideal HRV solution for air exchange and filtration in medium-sized shared environments. Its action helps effectively mitigate the presence of radon gas, restoring comfort and healthiness.

The Radon line HRV, small size and advanced performance
Flow400-R is the community HRV designed to intelligently address radon gas containment needs in medium-sized confined spaces: offices, co-working spaces, waiting rooms, small businesses and classrooms. Being just 22cm thick, Flow400-R is easily applied both vertically and horizontally, blending harmoniously with all environments

Configuration flexibility, for every need
The innovative Helty Flow400-R HRV system is distinguished by the flexible operating configuration of the ventilation unit. Using differential airflow rate adjustments, designers can set the most effective ventilation strategy, counteracting radon gas specifically in different rooms.


Even smarter with dedicated sensors
Flow400-R is even smarter in conjunction with the optional Radon Monitor sensor. The action of the sensor allows the HRV unit to adopt adaptive strategies to regulate airflow rates, automatically adjusting the volume of air treated in the delivery and suction points to achieve set threshold goals. The HCloud web app, paired with optional sensors, constantly monitors all indoor air quality parameters and can be used to remotely control each unit individually, setting different operation modes as needed.
