Frequently Asked Questions, FAQ

Can drafts occur when the Ventoxx HRVs are operating?

We recommend installing Ventoxx HRVs in pairs as the principle of operation is based on the simultaneous operation of two devices in different directions, one for fresh air intake and one for exhaust air.
The occurrence of drafts in their operation is completely excluded, as the airflow movement in one device does not exceed 0.15 m/sec.
