Ceramic heat exchanger
A high-efficiency ceramic core stores heat from outgoing air and returns it to incoming air.

01Overview
Fresh air, without
the ductwork.
Zephyr ventilates a single room through the wall, in buildings with no ventilation ductwork. At full speed it moves 60 m³/h on 5.9 W.
A reversing fan and a ceramic heat exchanger let it recover heat while it ventilates. Several units can run in sync over Wi-Fi.
Dual-flow fan technology
The fan reverses direction every half-cycle to alternate extract and supply.
Up to 90% efficiency
Up to 90% thermal efficiency for comfortable air at low energy cost.
Low consumption
0.9 W in night mode, 5.9 W at full speed (60 m³/h).
Synchronised units
Multiple units connect over Wi-Fi to run in sync for larger spaces.
Year-round operation
Operating range −25 to +40 °C, with an IPX4-rated enclosure.
02How it works
A 70-second cycle
that keeps the heat in.
Zephyr alternates airflow direction. The ceramic core charges with heat on the way out and releases it on the way in.
One full cycle takes 70 seconds. The animation runs faster.
