Temp-Vent-Series 5 Automatic Foundation Vents - Black

If there’s one thing termites are attracted to, it’s warm, moist, dead air environments such as those found under houses in crawl spaces or unfinished basements.

Temp-Vent foundation vents are designed to provide ventilation that can reduce moisture in these areas, which helps control termites. Powered vents are quick, convenient and economical when it comes to helping to solve moisture, mold and odor problems. Air is suctioned out of the crawlspace and replaced with fresh outside air. Negative pressure helps prevent dampness and odor from rising into living areas of the home.

The non-powered, Automatic Foundation Vent will open and close automatically using a heat/cold sensitive coil. The louvers open completely at approximately 72°F and completely close at approximately 38°F. Unlike manual vents that can waste energy when no one remembers to open or close them, these vents self-adjust all year long.

It's a crawl space dehumidifier with no drain or power needed!
