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. Our most popular models include an adjustable Dehumidistat for automatic operation, a freeze protection thermostat and a 6 foot power cord.
