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.

Frequently asked questions

A wall-mounted CMV can be installed quickly and without costly work. Simply drill two 80mm cores on the perimeter wall, prepare the power supply and fix the unit to the wall using screws and dowels.

The installation templates for Helty Flow wall-mounted CMV models are available for download in the reserved area and include holes distances, coring dimensions and overall dimensions.

No, none of the models in the Helty CMV range require a condensate drain

A decentralised dual-flow CMV allows for continuous replacement of extracted stale air with fresh air intake, meaning better results in terms of energy efficiency and purification of incoming air.
