Description

this product was made in americaRemove moisture and avoid the musty, stagnant air associated with many basements and crawlspaces with the Tjernlund V2D. Adding this fan-powered crawlspace ventilator will increase ventilation and vent out various unwanted items like radon, off-gassing and odors to keep them out of your main living space.

Protect Your Home & Your Family

Air quality starts from the ground up, so ventilating your crawlspace and basement is important to your overall air quality. When you install this ventilator, two fans and a large faceplate attach to a vent to push musty air out of your space. It can be installed in pre-existing vents in your crawlspace and includes a thermostat and dehumidistat so you can check your air quality at anytime. Damaging moist air will be pushed out of your crawlspace through a rugged outdoor hood. 

At an affordable price point, you can avoid dangerous indoor air issues from damaging your home’s interior and negatively influencing your health.

tjernlund fan airflowHow it Works

Use the on-board dehumidistat to set your ideal humidity level in your crawl space. In addition to turning the unit on or off, you can select your humidity between 20% and 80%. Once the humidity falls below your set level, the fan automatically turns off and then will turn back on once the humidity level rises above that set mark.

Installation

You can install this American-made product anywhere within 6 feet of a standard outlet. It’s designed to be placed directly behind standard vent openings. The power cord is included with purchase, and the dimensions are 18 x 9 x 2 inches (L x H x W).

How Many Does Your Crawlspace Need?

If you have a large crawl space, you may need more than one Tjernlund UnderAire V2D Crawl Space Ventilator. To determine this, Tjernlund suggests you find out how much CFM you need. Each model provides up to 220 CFM.

To determine what CFM your space requires, follow this formula: Multiply the square footage by the height (to get the cubic feet) and then divide that number by 15. This gives the amount of CFM you need to properly ventilate your space.

Additional Features

  • Fan Performance: The powerful fans offer 220 CFM of air movement, making it Tjernlund's most powerful crawlspace fan in their line.
  • Freeze Protection Thermostat: Freeze protection turns on to protect this model from freezing when the temperature hits 40 degrees. The thermostat won't allow this model to work under 40 degrees F and will cut on operation at 50 degrees F. 
  • Dehumidistat: You can turn the humidistat on or off and also set it from 20 - 80% relative humidity.
  • Removable Screen: A screen attaches to the outdoor hood to avoid bugs and other irritants from entering your crawlspace. 

Summary

Air quality starts in your crawlspace, and this model avoids moist, stagnant air from taking over the base of your home.

What Customers Love

  • Automatic Control: Out of sight, out of mind. Set your dehumidistat and the V2D will only run when needed.
  • Made in America: Manufactured in America, this is a trusted product with long warranty.

Things to Consider

  • Crawlspace Size: Depending on how large your space is, consider adding a second one to provide enough CFM to move the air properly.

    Yes, thinking about buying a second unit as well.

    Works wonderful in my 4 ' crawl apace. As I have two small vents down there, but no exhaust fans. And with the climate here.zone 5b, the moisture [humidity] is greater than before. And much needed in removing excess condensation. thanks

    I will use Sylvane again. Very easy to work with.

    We will be installing this fan in a crawlspace that we are mediating water intrusion issues. The customer service and shipping was over the top. We will definitely use Sylvane in the future.
