ATMOX Foundation Vent Cover – Solid – Internal Mount

The foundation vent cover is for use in a crawl space to keep air flow blocked from the outside.  In order to create improved cross circulation, the crawl space needs fans. Many crawl spaces cannot get enough ventilation through passive open vents. Therefore, fans are used to circulate and exchange air. Often in creating a cross circulation of air, it can be beneficial to block vents to make sure that the air flows all the way across the crawl space. Additionally, vent openings that are under decks and porches are often a great source of moisture in the crawl space. As a result, the recommendation is generally to block those off.

The ATMOX system offers the best crawl space moisture control system through the use of smart ventilation and dehumidification. The fans will run at optimal times with the use of the ACE Controller. With the ATMOX controls, low voltage 12V DC wire gets power to the fans. Therefore, the setup of all components (not including a dehumidifier) will run from one electrical outlet. This allows for simple installation, and minimizes or eliminates the need for an electrician at the installation.

The vent covers are sold in a 5-pack.
