ATMOX Crawl Space Vent – Open – External Mount

This crawl space vent fits in any standard 16 by 8 inch vent opening. The vent cover mounts from the outside and tightens in place with four screws. This vent cover is open to allow air flow to come through. Additionally, these match the vent covers used in our 145 CFM External Mount Fan with Vent Cover. It is also the same vent cover as used in our Solid Vent Cover.

These crawl space vents are one 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 only at optimal times with the use of the ACE Controller. All ATMOX products are designed with an emphasis on energy efficiency because crawl space ventilation systems 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.

An AC Adapter powers these fans in a standard outlet. In this setup, the crawl space fans will run continuously.

Includes 3-year limited product warranty
