Details

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. All Ventilator models are equipped with a factory installed and pre-wired thermostat which will prevent operation of the fan below 35°F.

Includes one crawlspace ventilation fan and large faceplate sized for ventilation openings through block foundations. Also includes thermostat, dehumidistat and pre-wired 6' power cord.
Deluxe models are controlled by a dehumidistat which actuates the fan if the relative humidity rises above the selected set-point.

Additional Information

Specifications	Dimensions: 18" x 9" x 2" Capacity: 110 CFM Motor: 115 Volts ~ 50/60 Hz Thermostat: On at 50°F, Off at 35°F Dehumidistat: 20% -80% RH Range
Additional Information	Important: Calculate the cubic area of the crawl space by multiplying the length x width x height. Divide this number by 15 to determine the minimum CFM necessary to fully ventilate the space in 15 minutes. Example: 20' wide x 40' long x 3' high crawl space = 2,400 cubic ft. 2400 cubic ft. divided by 15 minutes = 160 CFM of ventilation. Choose two V1 or V1D ventilators or one V2D ventilator. For general ventilation use only. Do not use to exhaust hazardous or explosive materials and vapors. Mount Crawl Space Ventilator inside the crawl space behind existing foundation ventilation openings. Ventilation openings shall be within three feet of each corner of the building. Screws and masonry wall anchors are included. Installation Instructions
