BSK Zephyr decentralized heat recovery device is a ventilation solution designed for rooms without an existing ventilation infrastructure. It is easy to install, has very low noise and energy consumption, and comes with built-in wireless connection features.

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 wi-fi, and you can control your devices with the included IR remote.
