UnderAire Crawl Space Ventilator - Hardwire

Use a crawl space ventilator to exhaust damage causing moisture to the outside.  Excess moisture can cause multiple problems such as mold, mildew and wood rot which can add up to costly repair projects to support columns, joists and beam supports.  Excess humidity in a crawl space can also lead to increased termite activity.

This Model belongs to the line UnderAire crawl space ventilators from Tjernlund.  The V1 does not have a plug, which allows you to hardwire it yourself. Model V1 does not include a dehumidistat, but one may be added.  This model does have a thermostat which prevents the fan from operating when it is less than 35 degrees.  You may wire multiple fans to a single switch or dehumidistat.

This crawl space ventilator is made in the United States and is very easy to install

  • 110 CFM
  • Motor: 115 Volts, 50/60 Hz, 0.30 amps maximum

  • Dimensions: 14 3/8" x 6 7/8" x 2"

How to determine the number of crawl space Ventilators you need:
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 crawl space ventilators or one V2D crawl space ventilator.

Question: Is this product to exhaust or supply or can it be switched either way?
Answer: This fan exhausts the fan out of the crawl space but draws fresh air in through open vents.
Question: Can the fan be reversed to supply air into space?
Answer: No.
