The aroVAIR wall hung fan coil exemplify versatility, making it suitable for all types of rooms in the house, needing efficient climate control. Designed for both new builds and modernised homes, these fan coils provide exceptional heating, cooling, dehumidification and ventilation with remarkable speed. Whether in living rooms, kitchen, aroVAIR casettes ensure tailored comfort throughout the year, by perfectly and efficiently partnering with aroTHERM heat pumps. They function independently or can seamlessly complement underfloor heating and radiator.

All-in-one indoor climate comfortHeating, cooling, ventilation and dehumidification for year-round comfort.
All-in-one indoor climate comfort
aroVIAR fan coils can heat or cool a room depending on the season, while also providing ventilation and removing excess humidity — all in a single unit. When combined with a reversible heat pump such as the aroTHERM, they deliver complete ambient comfort throughout the entire year.
Designed for maximum heat-pump efficiencyPerfect compatibility with Vaillant aroTHERM heat pumps.
Designed for maximum heat-pump efficiency
aroVAIR fan coils are the ideal complement to aroTHERM heat pumps. They transfer the heat or cooling provided by the reversible heat pump, allowing you to take full advantage of the technology. In addition, they enable the heat pump to be operated under ideal conditions, maximising its energy efficiency.
Simple, water-based installationNo refrigerants or gas handling required.
Simple, water-based installation
As with traditional radiators or underfloor heating, only water circulates between the indoor unit of the heat pump and the fan coils to provide heating or cooling. No refrigerants or gas are used, making installation and maintenance simpler and allowing the work to be carried out by your usual installer.
Space-saving wall-mounted designCompact installation that frees up living space.
Space-saving wall-mounted design
The wall‑hung aroVAIR units are typically mounted at a height of over 2 metres, freeing up the lower part of the walls. This creates valuable space to position furniture and decoration without obstruction.
Fast response with quiet operationRapid temperature control with minimal noise.
Fast response with quiet operation
By using controlled, comfortable pulsed air to heat or cool the room, aroVAIR quickly reaches the desired temperature with very little inertia. It adapts rapidly to changing conditions, including ventilation needs and humidity removal. The unit features a silent fan with adjustable operating speed, which runs even quieter at night – ideal for bedrooms.
Flexible comfort controlWired or wireless operation for personalised settings.
Flexible comfort control
Temperature, ventilation, fan speed, and air sweep orientation can all be easily adjusted using the wired controls connected to aroVAIR or via remote wireless control, giving you full flexibility to tailor your comfort.
Comfort and efficiency modesOperating modes for the ideal balance of comfort and savings.
Comfort and efficiency modes
The aroVAIR control menus allow for adapting their operation to different situations – either continuous or intermittent. Depending on the setting, the unit can prioritise rapid distribution of hot or cold air, or switch to silent and economical modes, ensuring the ideal balance between comfort and energy savings in every scenario.
