Wall-mounted mini recuperator BSK Zephyr Mini

Mini recuperator BSK Zephyr Mini – smart ventilation for small spaces

Efficient ventilation without heat loss is not an option in modern homes, but a necessity. Without a central ventilation system, humidity, harmful particles, and stale air accumulate in the rooms. This can lead not only to poor well-being, but also to long-term damage to the structures of the rooms.

BSK Zephyr Mini is a high-class mini recuperator, specially designed for bathrooms, kitchens, cloakrooms or other small spaces. It not only ensures a supply of fresh air, but also retains up to 90 % of indoor heat, reducing energy losses during the cold season. It is a smart and sustainable alternative to traditional ventilation.

How does BSK Zephyr Mini work?

The recuperator operates in cycles: every 70 seconds the direction changes between extraction and retraction modes. At this time, the ceramic heat exchanger in the device absorbs the heat of the exhaust air and transfers it to the incoming fresh air. This preserves heat and keeps the air constantly circulating - even with sealed windows.

• Operating efficiency – up to 90 %;
• Maintains a stable temperature regardless of the season;
• Three air flow rates – 15, 20 and 30 m³/h. 

Modern design and smart control

Mini recuperator BSK Zephyr Mini stands out not only for its functionality, but also for its elegant design, which easily fits into a modern interior. Control is simple and convenient - the device can be controlled:

• Remote control;
• By smartphone via the BSK Connect mobile app (Android / iOS) in Lithuanian!

The smart app allows you to:

• Monitor air quality in real time;
• Set a weekly ventilation schedule;
• Select humidity control level (40 %, 60 %, 80 %);
• Receive filter replacement reminders.

Smart system – more than one device

Mini recuperator BSK Zephyr Mini can be linked with other devices of the same series to operate as a smart zone ventilation system. One device can become the “master”, and the others will operate synchronously: when one device draws in air, the others automatically switch to exhaust mode. Such a scheme allows for efficient air circulation between rooms and creates constant, balanced ventilation throughout the home – without a centralized system.
