## Description

The Tjernlund UnderAire Series V2D Crawl Space Ventilator fan is designed to circulate fresh outdoor air underneath homesand 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 alsocause plumbing failures due to rust and corrosion. Constant operation helps vent radon gases, treated wood off-gassingand other odors that might migrate into living areas. The V2D is controlled by a dehumidistat whichactuates the fan if the relative humidity rises above the selected set-point.

• Made using high-grade galvanized steel for durability
• Efficiently ventilates crawl spaces to remove excessive humidity
• Thermostat averts operation of fan below 35°F outdoor temperature
