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


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


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


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.

Easy to install

Can be used as standard on walls from 250mm to 500mm and can be extended up to 1000mm with the pipe extension accessory. The pipe diameter is 160mm and recommends a hole diameter of 165mm
