How does FTX work?

Ventilation keeps oxygen levels inside the apartment adequate and extracts harmful fumes and odors outside. Incoming air is always filtered through high quality filters so that indoor living is healthy and comfortable. With intelligent ventilation you guarantee fresh and healty air, save energy and prevent problematic moisture.

With over 400 000 air handling units delivered, Swegon provides
fresh and healthy air to millions of people every day.
Solutions tested in high tech laboratories and proven in the
Scandinavian arctic weather conditions to guarantee supreme
energy-efficiency and a healthy indoor climate in all circumstanc

HIS IS HOW IT WORKS

Extract air is removed from the apartment through the extract valves and ducting to the ventilation unit. The extract air is taken from those parts of the apartment that have the highest amount of substances harmful to air quality such as the wc,kitchen and bathroom. The air continues inside the unit to the built-in heat exchanger which recovers the heat energy from the extract air, passes the extract air fan and is sent outside as exhaust air.

Ventilation layout

Simultaneously fresh and cold outside air enters the unit, passing through filters that remove all harmful substances, and continues to the heat exchanger where it is heated up by the recovered heat. Finally it is distributed through supply air ducts and diffusers to the apartments supply air. 

R3 how it works

The most efficient CASA units use less than 85W of energy at an airflow of 65 l/s, which is just slightly more than the use of a traditional light-bulb. With that energy the heat exchanger creates a temperature rise of 36 °C in the supply air, from -20 °C to +16 °C.

Poor air quality can lead to nausea, headache and even serious diseases to our respiratory organs. Efficient ventilation keeps oxygen levels adequate and extracts harmful fumes and odors. Incoming air is always filtered through high quality filters so that indoor living is healthy and comfortable.


In the olden days we simply opened the window for fresh air. But this way we lost a significant amount of heat energy. With intelligent heat recovery systems you can recover up to 89 percentof the exhaust air heat energy to use to heat the incoming fresh air. Intelligent ventilation does not waste energy, but re-uses it to create free heating or passive cooling and saves household energy costs.


Inadequate and unbalanced ventilation can lead to increased moisture levels that provide a habitat for harmful microbes and molds. Intelligent ventilation extracts excess humidity from indoor air and makes sure that uncontrolled pressure differences don’t create a risk of moisture in the the building envelope.
