Positive Pressure

No Roof Space

This system takes air from outside and using a fresh air heater / dehumidifier pushes warm dry air through the house which raises the air pressure slightly pushing out moist air which causes dampness and condensation.


Moisture in the home is created in many ways, damp winter air, breathing, cooking, showering, clothes drying  and more.


Remove your damp air today, install a Drivaire Home Ventilation System

Now you can have a warmer,  drier and healthier home even if your house has no roof space such as a Lockwood or similar design.
