Tjernlund V1  Model UnderAire Crawl Space Fan Ventilator, 110 CFM

Excess moisture in crawl spaces causes mold, mildew and wood rot with the resultant odors often migrating to the living space above. Crawl space fans quickly exhaust moisture and odors to the outdoors through existing passive vents. Includes a freeze protection thermostat to prevent operation when outdoor temperatures are below 40 degrees F.
