Air distribution system for heat recovery ventilation
The ARIA CONNECT and ARIA FLAT 500 plastic duct systems are energy-efficient solutions for heat recovery ventilation, ensuring clean and fresh indoor air thanks to the use of the Ultra-Fresh® antibacterial additive. The range includes round ducts with diameters of 63 mm, 75 mm and 90 mm (ARIA CONNECT), as well as a system based on flat ducting (ARIA FLAT 500).
The solution has been developed based on many years of expert experience and high-quality components and, when combined with the ARIA ADURO system, forms a complete air distribution system for HEATPEX ARIA mechanical ventilation with heat recovery.
What other advantages make this solution stand out?
Firstly – Investors and Installers can efficiently design the system infrastructure using the intuitive ARIA PLANNER application, which in three simple steps facilitates the preparation of project documentation and a list of required materials.
Secondly – the system incorporates proprietary OneClick® technology, enabling fast and trouble-free installation without the need for specialist tools.
Thirdly – the solution meets the most restrictive ATC1 airtightness class, ensuring lower noise levels and an energy-efficient heat recovery system.
Fourthly – the possibility of combining round and flat duct systems, as well as using different duct diameters within a single installation.

The HEATPEX ARIA CONNECT 90 mm plenum box with OneClick® technology is a ventilation system component used for installing supply and extract air diffusers.
It is manufactured from durable and lightweight polypropylene (PP – virgin raw material), ensuring reliable long-term operation without the risk of mechanical damage thanks to a specialised plasticiser additive. The material is 100% recyclable.
If there is sufficient space to install the 90 mm duct system, the benefits include higher airflow capacity — the recommended value for a 90 mm duct is 45 m³/h (compared to 30 m³/h for 75 mm) — as well as lower pressure losses, quieter operation and fewer ducts required throughout the building.
- Suitable for installation within the floor structure or beneath the ceiling in suspended ceilings.
- Sockets with gaskets and rings in the OneClick technology® (2x90 mm in basic configuration) allowing for quick and convenient installation of ventilation pipes.
- Adaptable mounting flaps with height adjustment.
- Smooth airflow adjustment thanks to a dedicated damper.
- Ribs for easy cutting.
- High mechanical resistance thanks to the use of a specialized additive in the form of a plasticizer.
- The highest airtightness class - ATC1 according to PN-EN 17192.
The plenum box includes the following components *:
- Main body – 1 pc.
- 2x90 module with elliptical seat gasket – 1 pc.
- Mounting ring for the pipe with gaskets – 2 pcs.
- End plug with gasket – 2 pcs.
- Adaptable mounting blade with screw – 2 pcs.
- Cover of the approach under the diffuser – 1 pc.
*) The plenum box is supplied as a factory-assembled unit.

HEATPEX ARIA CONNECT / FLAT500
TOP AIRTIGHTNESS CLASS (ATC 1)
Quiet and energy-efficient HRV system
Through the use of appropriate materials and the patented OneClick® connection system between individual system components, the highest airtightness class (ATC1) according to the PN-EN 17192 standard has been achieved. This means that the airtightness of the ductwork is three times higher than that of class D.
This performance is achieved without the use of any additional sealing materials during installation. The ATC1 airtightness class has been confirmed by tests carried out by an independent laboratory, making the system one of the first — and still the only — solutions on the market to meet this most restrictive standard since 2019.
As a result, users benefit from lower noise levels and increased energy savings.
INSTALLATION FASTER THAN EVER BEFORE
ONECLICK technology®
OneClick® technology is a proprietary connection system developed by HEATPEX. It allows all heat recovery components to be joined without tools. Should your plans change during installation, parts can be easily disconnected and reused with no risk of damage.
ANTIBACTERIAL COMES AS STANDARD
Breathe fresh and clean air at all times
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.
The antibacterial additive from a renowned manufacturer, whose main component is silver phosphate glass, is also used by over 300 global brands across 50 countries worldwide.
In addition, an antistatic additive and smooth inner surface of the air duct keeps dirt deposits to a minimum.
The high level of hygiene of the ARIA system is confirmed by the National Institute of Public Health – PZH.
HIGHLY CUSTOMISABLE
6 basic elements only
The modular design of the system makes it easy to customise its parts to the specific requirements of any building. This helps to reduce the number of parts which are left unused, to limit the space taken by the ventilation system to a minimum and to keep the costs of the entire project as low as possible.
The ability to combine flat and radial ducts, as well as multiple diameters within one system, ensures optimised airflow and greater installation flexibility.
Distribution boxes can be connected horizontally or vertically, increasing the number of slots needed.
OPTIMAL INSTALLATION
Possibility of combining different diameters: 63 mm, 75 mm, 90 mm and, also flat duct system 50mm
The ARIA CONNECT radial duct system offers flexibility in designing ventilation installations, allowing the combination of ducts with diameters of 63 mm, 75 mm and 90 mm, as well as integration with the ARIA FLAT 500 flat duct system — even within a single floor. This enables optimal adjustment of the installation to the building layout and 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, making them ideal for bedrooms, living rooms and larger spaces. The ARIA FLAT 500 flat duct, with a height of only 6 cm, is perfectly suited to areas with limited installation space.
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 and walk-in wardrobes. Combining them with the flat duct system (with an overall height of just 6 cm) increases design flexibility and enhances the aesthetic appearance of the installation.
DISCOVER ALL ADVANTAGES OF ARIA
LOW NOISE LEVEL
The optimal air flow through different parts of the system and double wall pipes helps to reduce the level of noise generated by the flowing air, which matters especially during the night.
DURABILITY & STRENGTH
The system components are made of extremely light yet durable plastic material ensuring reliable operation for years, without the risk of mechanical damage or corrosion.
More importantly the construction material used (PP – polypropylene) is considered safe as it poses no health hazard and is 100% recyclable.
LOW PRESSURE LOSS
The careful design of each single part of the system and smooth inner surface of the pipes allow to keep the system’s pressure loss low.
COMPACT SIZE
The small size of the HEATPEX ARIA CONNECT and ARIA FLAT500 systems allows to conceal the parts of the system in the ceiling, either in the insulation layer covered with screed or inside the plenum space if a dropped ceiling is used.
The height of the distribution box is only 10.6 cm.
