The BSK Zephyr room heat recovery unit operates on a two-way fan principle, allowing it to recover heat through a ceramic heat exchanger. With a power consumption of just a few watts and thermal efficiency of up to 90%, this unit meets your ventilation needs while also providing energy savings. The device works in 70-second cycles, alternating between intake and exhaust. As the air is expelled, the ceramic heat exchanger heats up, and when the air flow direction reverses, the stored heat is used to condition the incoming air.
