The crawl space ventilation unit ventilates the entire crawl space, controls the airflow by utilizing replenishment air exclusively from the upper levels, and maximizes air circulation. The unit extracts moisture and air pollutants out of the crawl space and maintains a drier and healthier environment in the crawl space so it will no longer be a source of problems in the entire house, says the company. The system comes with balanced air replenishment, controlled ventilation that initially expels the air at a high rate, until favorable conditions are achieved. Once achieved, it will ventilate at a low rate to create mandatory air exchanges throughout the house and control the conditions in the crawl space. According to the manufacturer, by adjusting ventilation rates, the energy impact is minimal and actually increases HVAC efficiency, as the equipment is operating in a drier environment. The units are easy to install and are automatically controlled.
