BSK Heat recovery unit, Zephyr Mini, ceramic, alternating flow, 4 operating modes, 2 G3 filters, tube length 250-500mm, Ø94, mounting hole Ø110

BSK Zephyr Mini recovers heat using a bidirectional fan and a ceramic heat exchanger.

The device operates in a 70-second cycle, alternating between air extraction and supply. In the extraction phase, warm air from the room heats the ceramic core. When the airflow reverses, fresh air from outside passes through the heated core and enters the room in a conditioned state.

With a power consumption of only a few watts and a thermal efficiency of up to 90%, BSK Zephyr Mini helps you save energy while ensuring efficient ventilation.

Multiple units can be connected via Wi-Fi and controlled using the included IR remote control.

BSK Zephyr Mini Heat Recovery Unit – Smart Ventilation with High Efficiency

BSK Zephyr Mini is a modern alternating-flow ventilation solution designed to maintain a healthy indoor climate and reduce energy consumption. The system uses a bidirectional fan and a ceramic heat exchanger, capable of recovering up to 90% of the thermal energy from the exhausted air. This significantly reduces heat loss and lowers heating costs.
The device operates in an automatic 70-second cycle, alternating between air extraction and intake, ensuring permanent and balanced ventilation.

Recommended Use

BSK Zephyr Mini is ideal for:

• Controlled ventilation of residential and commercial spaces;

• Air refreshment in bedrooms, living rooms, offices, or kitchens;

• Prevention of condensation and mold formation in living spaces;

• Well-insulated rooms or those with very tight windows, where natural ventilation is insufficient;

• Individual use or in multiple Wi-Fi synchronized systems.

Thanks to its compact dimensions, the unit can be integrated directly into the wall, suitable for both new constructions and renovations.
