Product details

Tjernlund V2D UnderAire™ 18" H X 9" W Silver Galvanized Steel Crawl Space Fan Ventilator

The Tjernlund UnderAire™ Series Crawl Space Ventilators are designed to circulate fresh outdoor air underneath homes and porches. 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. Constant operation helps vent radon gases, treated wood off-gassing and other odors that might migrate into living areas. Deluxe models (V1D & V2D) are controlled by a dehumidistat which actuates the fan if the relative humidity rises above the selected set-point. IMPORTANT: All Ventilator models are equipped with a factory installed and pre-wired thermostat which will prevent operation of the fan below 35°F outdoor temperature. Normal operation of the fan will resume once the temperature outside rises near 50° F.
