The Bosch fresh outside air damper system allows
fresh air to be introduced into the home for natural,
healthy ventilation. As the building codes of
residences are getting more restrictive on air

air can only enter the house as doors and windows
are opened. This typically lends to overused,
re-circulated stale air. Depending on the amount of
air that is being exhausted through the bathroom
fans, kitchen hoods, and local code requirements;
outdoor air may be required as make-up air for your
home. Bringing in outside air improves the overall
indoor air quality for you and your family.
