BSK Zephyr Mini 100 mm 30 m³/h – Single-Room Heat Recovery Ventilator
Smart ventilation for apartments, bedrooms, and smaller rooms
The BSK Zephyr Mini 100mm 30m³/h is a compact single-room heat recovery unit that helps bring fresh air into a room while reducing heat loss caused by ventilation. The unit is ideal for apartments, bedrooms, home offices, closets, bathrooms, or smaller commercial spaces that lack a traditional ventilation system.
The BSK Zephyr Mini uses heat recovery technology with a ceramic heat exchanger and achieves up to 90% heat recovery efficiency. The unit operates very quietly and is well-suited for use in a bedroom.
Why Choose the BSK Zephyr Mini?
- Heat recovery of up to 90%
- Very low energy consumption
- Quiet operating mode for the bedroom
- WiFi Control and Remote Control
- Easy installation on an exterior wall
- Suitable for apartments and buildings undergoing renovation
- Helps reduce moisture and condensation
- Filters the incoming air
- Compact and modern design

How does the BSK Zephyr Mini work?
The BSK Zephyr Mini operates in 70-second cycles. First, the unit removes warm, humid air from the room through a ceramic heat exchanger. Then the fan reverses direction, and fresh air from outside flows through the preheated ceramic element back into the room. This preserves a large portion of the heat and allows fresh air to enter the room with lower energy consumption.
The ideal solution for the following problems
The BSK Zephyr Mini helps:
- reduce stagnant air
- improve the indoor climate
- reduce moisture
- reduce condensation on windows
- to help with mold problems
- ensure a supply of fresh air
It is particularly well-suited for rooms where:
- There is no proper ventilation
- the windows are fogging up
- The air feels still
- There is a high level of CO₂ in the room
- It is not possible to install a central ventilation system
Very quiet operation in the bedroom
One of the biggest advantages of the BSK Zephyr Mini is its quiet operation. In night mode, the noise level can be as low as about 17 dB(A) at a distance of 1 meter.
This makes the device a good choice:

What is the BSK Zephyr Mini ventilation system with heat recovery?
The BSK Zephyr Mini heat recovery ventilation system ensures healthy and clean air in your home. The system provides a constant supply of fresh air while simultaneously removing contaminated air. What makes this system unique is that it saves energy by recovering heat. This means you need less heating, which results in lower energy bills.
How does the BSK Zephyr Mini heat-recovery ventilation system work?
The BSK Zephyr Mini heat recovery ventilation system works as follows: Warm, humid air is drawn out of the room and vented outside. As this happens, the heat exchanger automatically heats up so that no heat is lost from the room when the process is reversed. By reversing the process every 70 seconds, fresh air is drawn into the room while contaminated air is extracted from it. The unit’s 5% heat loss makes it one of the most efficient heat recovery systems currently available on the market. In addition, the system is equipped with sensors that automatically measure temperature and humidity levels. If these values are too high, the system automatically draws in more air and supplies fresh air. This means that air quality is continuously monitored and regulated.
