ATMOX Crawl Space Vent Cover – External Mount – Solid – Open

This crawl space vent cover fits in any standard 16 by 8 inch opening. The vent cover mounts from the outside and tightens in place with four screws. This vent cover has a solid back to keep air flow blocked from the outside. The solid plate behind the grill is removable to use as an open grilled vent cover. Often in creating a cross circulation of air with fans, 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. Therefore, the recommendation is generally to block those off.

These vent covers will match the vent covers used in our 220 CFM Fans made to  Vent Cover. The solid plate is removable to use as an open grilled vent.

These crawl space vent covers are one optional component of the ATMOX System. 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. All ATMOX products are designed with an emphasis on energy efficiency, because crawl space products should be effective and inexpensive to operate.

With the ATMOX controls, a 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.

Vent Covers are sold as a 5-pack.

Includes 3-year limited product warranty.
