Tjernlund V1D underaire crawl space ventilator 110 cfm
Tjernlund V1D Underaire Crawl Space Ventilator. Fan powered crawl space ventilation quickly reduces moisture helping to protect both home and occupants.
* Ventilates excess moisture, the cause of mold, mildew and wood rot. Increase air circulation to fight condensation.
* Constant operation helps vent radon, treated wood off-gassing and odors that might otherwise migrate into living areas
One fan and large faceplate sized for ventilation openings through block foundations. Includes thermostat, dehumidistat and pre-wired 6' cord.
How to determine the number of UnderAire Ventilators needed:
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. 15 minutes = 160 CFM of ventilation. Choose two V1 or V1D ventilators or one V2D ventilator.
