FRESH AIR & FILTRATION
Fresh air where
it matters
Filtered air reaches living rooms and bedrooms while stale, moisture-laden air is extracted from kitchens, bathrooms and utility rooms.
SUMMER BYPASS
Respond to
warmer weather
The bypass avoids reheating cooler incoming air when conditions allow. It supports summer ventilation; it does not provide active cooling.
EC MOTOR TECHNOLOGY
Match airflow
to the home
Efficient EC motors provide adjustable fan operation, helping the commissioned system deliver the airflow required by the ventilation design.
