Vitoair FS mechanical ventilation system with heat recovery and humidity control

The Vitoair FS central mechanical ventilation system ensures a healthy room climate and pleasant temperatures throughout the house.

The increasing climate fluctuations of our time often have an impact on health. This makes reliable ventilation of your own four walls all the more important. The new Viessmann Vitoair FS mechanical ventilation system is the ideal solution.

The special features of the Vitoair FS

Compact, quiet and powerful

With its low installed height of 245 millimetres and a maximum air flow rate of 300 m³/h, Vitoair FS is not only especially slimline but also compact. It also features particularly quiet operation at high output.

Optimum indoor air quality thanks to heat exchanger

The special polymer membranes of the recuperative enthalpy heat exchanger in the Vitoair FS not only recover heat, but also moisture. This helps keep indoor air pleasant and contributes to a sense of wellbeing.
The water vapour molecules contained in the extract air diffuse through the membrane and are absorbed by the outdoor air on the supply air side. This reduces the amount of indoor air that is too dry or too humid. The fact that the polymer membrane also prevents the transmission of viruses, mould and bacteria makes Vitoair FS a hygienically perfect solution.

Straightforward installation and commissioning

There are a number of installation options: below the ceiling, on the wall or horizontally in the attic. The connector arrangement can be adapted to the respective conditions. No condensate drain is required. They also provide the option of enabling trade partners to monitor the system remotely and rectify faults either immediately online or by means of a quick service call.
