BSK Zephyr 110 Heat Recovery Ventilation Unit

🌀 BSK Zephyr 110 – Quick Info
Product type:
A decentralized heat-recovery ventilation (MVHR) unit designed to supply fresh air and remove stale air in rooms that don’t have existing ducted ventilation.
How it works:
The device uses a two-way fan and a ceramic heat exchanger to cycle air in ~70-second intervals. Warm indoor air is expelled while heating the ceramic core; when airflow reverses, fresh outdoor air passes through that core, retaining much of the heat — helping to ventilate with up to ~90 % heat recovery efficiency.
Key features:
• Designed for easy wall installation in single rooms without ductwork.
• Low energy consumption (just a few watts).
• Quiet operation with multiple fan speed levels.
• Includes Wi-Fi connectivity and remote control options in many variants.
• Digital temperature and humidity sensors help regulate operation.
Typical specs (for the similar 110-size model):
• Airflow stages: ~15–60 m³/h depending on setting.
• Power usage: ~1.2 – 6.3 W.
• Noise: low at typical indoor operating speeds.
• Suitable for wall openings with ~110 mm diameter (varies by exact variant).
Good for:
Small residential rooms, offices, or spaces where you want controlled ventilation with heat retention and low energy use without installing a full HVAC system.


Description
BSK Zephyr can recover heat by using a 2-way fan heating and cooling of the ceramic heat exchanger inside. The device operates on a cycle that extracts and supplies air in periods of 70 seconds. While the air is extracted out from the room, the ceramic heat exchanger will be heated, when the air flow direction is reversed and fresh air from outside is supplied to the room, thanks to the heat stored in the ceramic core, it will be blown inside in a conditioned manner. BSK Zephyr, whose power consumption does not exceed a few watts and can reach 90% thermal efficiency, also allows you to save energy while meeting your ventilation needs. You can connect multiple devices to each other via wireless communication, and you can control your devices with the included IR remote.

Energy Use

Unparalleled A+ rated 4-speed high-performance motor that uses as little as 1.2 watts of energy on night-time mode and only 6.3 watts on high boost

Silent Operation

True silent operation with an ultra-low 3.6 dBA on night-time mode and 27.3 dBA on high boost

Heat Recovery

The heat of the unit is a quality ceramic heat recovery core that provides long-term performance of up to 90 heat recovery

Humidity control

Integral humidity sensor with 3 humidity monitoring levels. When a set humidity is reached, the device will enter exhaust mode to dispense excess humidity.

Speed Control

4-speed settings from 15 m3/hr to 60 m3/hr including a night mode for silent operation

3 Ventilation Modes

Set your unit up for any situation with a press of a button and will allow for either heat recovery of up to 90% or simply extract warm or humid air or even just supply fresh air in from outside

Controllability

The unit comes with an IR remote control that allows you to control all the features on the one unit or any other additional units simultaneously

Filters & Maintenance

The system has been designed with extra quick and easy servicing of the two filters as the core and filters can be removed and cleaned without any tools or removing the outer covers

Anti-draft

During operation, the inner grille will open depending on the chosen airflow rate and if the unit is not being used the grille will close over with a foam seal

Wi-Fi

Built-in Wi-Fi enables wireless pairing of multiple devices across your house, when paired devices will run either in parallel or in reverse depending on your setup. When the primary device is in ventilation mode, all parallel devices will also follow, while the reverse devices will be in exhaust mode. This way you can have continuous ventilation and aspiration and create air drafts inside or across rooms to increase the effectiveness of ventilation. You can set different settings and speeds for different rooms and create various ventilation zones.
