The Tjernlund UnderAire Series Fresh Air Supply Fans for Crawl Spaces are designed to boost fresh outdoor air under-neath homes and porches. Use in conjunction with Tjernlund UnderAire Crawl Space Exhaust Fans to remove moisture in Crawl Spaces with too few or undersized passive vent openings, overall lengths of over 40 feet, or in “dead zones” or stagnant areas that are not served by existing foundation vents. Excessive humidity levels in Crawl Spaces is the leading cause of premature rotting of support columns, joists, floors and beam supports. Humidity can promote fungus growth and increased termite activity. Humidity may also cause plumbing failures due to rust and corrosion. Helps dilute radon gases, treated wood off-gassing and other odors that might migrate into living areas. All models are equipped with a factory installed and pre-wired freeze protection thermostat which will prevent operation of the fan below 35°F.
