Through the use of appropriate materials and a patented system of connections OneClick technology between the individual parts of the system, we have achieved the top airtightness class for the system (ATC1) according to the PN-EN 17192 standard. This means that the airtightness of the ductwork in our system is three times higher than that for class D.

This is achieved with outusing any additional sealing material during the installation works. The ATC 1 airtightness class has been confirmed by tests performed by an independent laboratory.

The entire HEATPEX ARIA CONNECT air distribution system is treated with the Ultra – Fresh® antimicrobial additives to make the air ducts resistant to microbes (99,99% reduction). This has been confirmed by independent lab tests according to  ISO 22196 standards.

An antistatic additive and smooth inner surface of the air duct keeps dirt deposits to a minimum.

The ARIA CONNECT system offers flexibility in designing ventilation installations, allowing the combination of systems with different diameters, even within a single floor. This enables optimal adjustment of the installation to the specific needs of each room.

Larger pipe diameters, such as 90 mm, can be used where maximum airflow efficiency and noise reduction are important — for example, in bedrooms or larger spaces on upper floors. These types of pipes can be easily hidden under the roof or in the ceiling, reducing the number of installation sections and lowering costs.

Smaller pipe diameters are ideal for hiding in ceilings between floors or in areas with dropped ceilings, and are well-suited for spaces where airflow requirements are lower, such as toilets under stairs or closets. While they may require more installation sections, they allow for more discreet placement of pipes in hard-to-reach areas.
