Frequently Asked Questions

  • What is a commercial MVHR unit?

    A commercial MVHR unit is a mechanical ventilation with heat recovery unit designed for larger buildings such as offices, schools, classrooms, retail spaces and commercial properties. It extracts stale air while supplying fresh filtered air and recovering heat from the outgoing air.

  • Where are commercial MVHR units used?

    Commercial MVHR units are commonly used in offices, schools, classrooms, meeting rooms, commercial buildings and larger ventilation projects where higher airflow rates are required.

  • Are commercial MVHR units the same as domestic MVHR units?

    No, commercial MVHR units are generally designed for higher airflow rates and larger spaces, while domestic MVHR units are designed for homes and smaller residential properties.
