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 is a practical, efficient ventilation solution developed for spaces without existing ventilation infrastructure — with easy installation, low noise and low energy consumption.
Dual-flow fan technology and a high-efficiency ceramic heat exchanger let it recover heat while it ventilates, and built-in wireless connectivity adds modern control.
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.
Minimal consumption
Consumes only a few watts of power in operation.
Synchronised units
Multiple units connect over Wi-Fi to run in sync for larger spaces.
Easy installation
Designed for straightforward installation with low noise in living spaces.
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 — shown here accelerated.
