Flow400 heat recovery ventilator

Flow400 is the innovative solution designed for the efficient ventilation of offices and shared spaces with an occupancy of up to 10 people. Compact and versatile, Flow400 ensures continuously filtered and renewed air thanks to its advanced filtration system featuring ePM1 80% filters, capable of capturing up to 80% of fine particulate matter smaller than one micron. Equipped with an enthalpy heat exchanger with heat recovery efficiency of up to 92%, Helty Flow400 can be configured with air flow rates ranging from 80 to 400 m³/h. With a sound pressure level of just 35 dB(A) at the design air flow rate, it is ideal for professional environments where particular attention to acoustic comfort is required. With an overall depth of only 22 cm, Flow400 is perfectly suited for retrofit applications in existing buildings and is available in the Steel version, featuring a steel cover designed for exposed installation, either wall- or ceiling-mounted. Optional humidity and CO₂ sensors enable continuous monitoring of indoor air quality, automatically adjusting the air flow rate according to actual needs. Integrated functions such as free cooling and night mode further ensure high efficiency and reduced energy consumption. The Flow400-R version enables optimal and efficient radon risk management, thanks to a dedicated technology specifically designed to dilute gas concentrations in confined indoor environments. Thanks to the Cloud platform, the unit can also be remotely controlled, allowing the configuration of customised scenarios and the execution of monitoring and control activities by Service Centres.
