Helty Flow800 is the ideal HRV system for ventilating larger spaces such as schools, kindergartens and crowded work spaces where it is essential to provide a continuous supply of outdoor air to improve the health conditions of the indoor environment.

Ductless HRV for schools to be designed

Flow800 simplifies the design of the air exchange system because it has no complex ducts.Installation requires two 250 mm cores on the building’s perimeter wall to manage air flows. Installation can be completed on existing buildings in a short time and without expensive construction work.

Comfort, health and energy saving

The Flow800 decentralised HRV system consists of an 800 m3/hour ventilation unit, which can be adjusted to 10 speeds to manage intermediate air exchange flows. Settable operating times and parameters allow you to set a weekly schedule.
The HRV unit has a cross-flow heat exchanger with 82% thermal efficiency that allows for air exchange without affecting the building’s energy performance.A double F9+G3 filter ensures maximum efficiency in purifying the external air delivered into the environment, preventing ingress of smog, fine particulates and pollens.

Healthy air for safer classrooms

Decentralised ventilation management prevents air recirculation that can allow pathogens to travel between environments.In addition, adjustable ventilation for each room means a more functional and efficient use of the system since the user can operate and regulate the settings according to the actual usage of the different environments.

Frequently asked questions

Mechanical ventilation allows for a continuous and sufficient replacement of the air volumes in enclosed spaces through stale air extraction and fresh air intake. This helps to reduce the presence of viral bioaerosols that might otherwise remain suspended in the air and spread by air.

Replacing indoor air with fresh air from outdoors that is continuously filtered and cleaned eliminates the problems associated with stale air, prevents the onset of mould and reduces the risk of exposure to dangerous indoor pollutants.

Natural ventilation through manual window opening is impractical, difficult to manage and energy-consuming. A mechanical ventilation system allows you to fully automate stale air removal and fresh air intake, delivering continuous indoor air purification and greater energy efficiency.
