Why do small spaces require thoughtful ventilation solutions?
In modern housing construction, it is increasingly difficult to find space for classic installation solutions. Tight construction, limited technical space and the desire for an aesthetically pleasing interior finish mean that the ventilation system must not only be effective, but also as compact as possible.
An additional challenge is the high airtightness of new buildings. Although it translates into lower energy losses, it simultaneously prevents natural air exchange. As a result, the risk of excessive moisture, decreased air quality and deterioration of occupant comfort increases. Traditional gravity ventilation under such conditions does not serve its purpose.
This is why there is a growing demand for compact recuperators that combine high efficiency, quiet operation and modern design. An example of such a unit is FlatAIR from Alnor.
FlatAIR from Alnor - what distinguishes this recuperator among compact models?
FlatAIR is a modern recuperator designed for apartments and condos where every inch of space matters. Compact, quiet and energy-efficient - it fits perfectly into the design challenges of small interiors.
With a height of just 170 mm, it can be easily installed in suspended ceilings or built-in furniture, without compromising on functionality.
The unit is available in a wide range of models with capacities from 80 to 250 m³/h, allowing it to be selected for both new apartments and retrofitted units. FlatAIR is also distinguished by its high quality workmanship. Energy-efficient EC fans, a lightweight and durable EPP housing and an optimized design guarantee quiet and stable operation for years.

Heat and moisture recovery technology - how does FlatAIR work?
FlatAIR uses a counter-current heat exchanger, available in two versions: standard (PET) and enthalpic - which also recovers moisture. Thanks to this, heat recovery efficiency can reach as high as 97.3%, which has a real impact on reducing heating costs. The system can be conveniently operated via a mobile app, and integration with CO₂ and humidity sensors makes it easier to maintain indoor comfort.
Installation and service in practice - what will designers and installers appreciate?
FlatAIR is designed for simple and flexible installation. The unit can be installed horizontally, in the ceiling or recessed, depending on the interior layout. Full access to service components is possible without removing the unit. Standard features include G4 filters (with an F7 option) and an RH sensor to support humidity control in the facility.
For whom will FlatAir be the best choice?
FlatAIR is a solution designed for projects where technical space is limited and expectations for comfort and air quality are high.
It will work well in residential developments, modern apartment buildings and compact single-family homes. Thanks to its low height and flexible installation options, it is also ideal for retrofitting existing buildings where there is no room for a traditional ventilation system.
It will also be appreciated by architects and investors pursuing premium projects, where not only efficiency, but also design, aesthetics of finish and acoustic comfort matter. FlatAIR works discreetly in the background, not interfering with interior design, while having a real impact on the quality of life of residents.
