Two series, one goal: clean air without energy loss.
Choose the right unit by airflow, placement and project — all with documented performance curves.
Better air where you live.
Balanced ventilation with heat recovery delivers a steady supply of fresh, filtered air — without draughts and without wasting heat. A healthier indoor climate all year.
Why demand-controlled ventilation? →Built on measurements, not assumptions.
Documented performance
Every unit comes with measured curves for airflow, pressure, SFP and sound level per octave band — right on the product page.
