Increased Airflow Capacity and Easy Installation
Flow ULTRA is the new continuous dual-flow ventilation unit from Helty, designed to serve individual rooms with adjustable airflow rates ranging from 15 to 120 m3/h. This decentralized HRV unit can be installed with two 100 mm diameter core drillings on the perimeter wall and comes with a standard white ABS cover for seamless aesthetic integration with the existing environment.
High Filtration Capacity and Thermal Efficiency
The continuous replacement of exhaust air with fresh air, combined with external air filtration using an F7 filter, creates a healthier and more comfortable environment by eliminating dust, odors, spores, and pollen. Energy savings are further enhanced by the enthalpy heat exchanger with efficiency up to 88%.
Available in Standard, PLUS, and ELITE Versions
All FlowULTRA models come standard with an infrared remote control for unit management. The Plus version is enhanced with the Air Guard app, equipped with a humidity sensor for automatic ventilation operation. The flagship model, FlowULTRA Elite, is tailored for those most sensitive to indoor pollution: it also monitors CO2 and VOC levels, automatically adjusting the airflow rate to ensure constant air hygiene.
