MaistAIR, a modern decentralized recuperator ensuring effective air exchange and high comfort of use. The device is equipped with a counterflow enthalpy exchanger, which allows for heat and moisture recovery, while effectively removing excess CO₂ and pollutants from rooms.

The recuperator ensures a constant air flow of 70 m³/h, making it ideal for flats, apartments, and rooms without ductwork. Built-in filters ensure air purity, and their replacement and device servicing are conveniently carried out from inside the apartment.

Quiet operation, a durable EPP housing, and intuitive control via a touch panel or mobile app make MaistAIR a practical and modern solution for residential buildings.

HRU-FlatAIR-Xwall, an advanced decentralised heat recovery unit that combines the technology known from central systems with a compact form and modern design. This solution has been designed for flats, studio flats and offices where it is not possible to install traditional ventilation ducts. HRU-FlatAIR-Xwall provides effective ventilation with heat recovery without the need to interfere with the extensive installation infrastructure.

Key features of the device:

• Enthalpy counterflow exchanger – technology characteristic of central systems
• Compact design allowing installation at any stage of interior finishing
• Galvanised steel casing, powder coated, lined with sound-absorbing foam – almost inaudible operation
• Innovative air control system – supply air at the bottom, extract air at the top, without mixing the air streams
• Possibility of supply and extract air through the front cover
• Customised front cover to match the interior design
• Option to order a central version with the possibility of connecting semi-flexible FLX ducts for air distribution between rooms.

HRU-FlatAIR-Xwall combines efficiency, aesthetics and installation flexibility – the perfect solution for modern residential and commercial spaces.

The FESP electrostatic filter is a new product from Alnor, designed for effective air purification in heat recovery systems. Thanks to its two-stage filtration technology, it removes over 95% of pollutants, including ePM1, ePM2.5 and ePM10 dust, providing high protection against smog. The steel pre-filter traps larger particles, while the advanced electrostatic filter with ionisation guarantees excellent efficiency with low flow resistance and minimal energy consumption. The device is maintenance-free, does not require cartridge replacement and can be cleaned with water. Its compact, insulated housing and high level of safety make the FESP filter the ideal solution for domestic mechanical ventilation.

The device is designed for domestic heat recovery systems:

• compact, thermally insulated housing,
• very low flow resistance,
• minimal energy consumption.

HRQ-4ZONE – a modern ventilation zoning system that is a natural evolution of the HRQ-2ZONE model. This solution is designed to meet the needs of energy-efficient and smart homes.

Key features and benefits of the HRQ-4ZONE system:

• Four independent ventilation zones – the ability to control up to eight anemostats in rooms using two HRQ-4ZONE-Connection-Box modules.
• Flexible configuration – when using a single module, the system operates in dual-zone mode, like the classic HRQ-2ZONE.
• Wireless communication – connection to the heat recovery unit and CO₂ sensors without the need for additional cabling.
• Automatic air flow control – supply and exhaust valves with precise control (accuracy up to 1 m³/h) adjust the ventilation intensity to current needs.
• Intelligent energy management – the system automatically limits the flow in unused rooms, reducing energy consumption.
• CO₂ sensors play a key role – they monitor air quality and the presence of users, allowing the system to dynamically adjust ventilation performance.
• Compatibility and expansion – the HRQ-4ZONE can be combined with the HRQ-2ZONE, which increases the flexibility of the system.
• Full compatibility with Alnor recuperators equipped with wireless automation and the Constant Flow module.

The HRQ-4ZONE system is another step towards intelligent, energy-efficient and comfortable ventilation in residential buildings.
