ATMOX Foundation Vent Fan – External Mount- 145 CFM – Intake Fan

The foundation vent fans mount from the outside of the crawl space in most standard vent openings that have a 16 x 8 inch opening. The fans replace any existing grill in the vent openings so they are aesthetically pleasing. Another benefit is the ease of installation of these fans from the outside.


Foundation vent fans are one component of the ATMOX System. ATMOX uses an ATMOX controllerfans and/or dehumidifier for the actual drying or moisture control. However, the ATMOX setup is not just fans and/or a drying unit. The ATMOX System is a smart solution using the  ATMOX ACE Controller, the brain of the system, to determine the best operation to improve conditions within your crawl space. It does this through analysis of the combination of dew point, temperature, and humidity. Therefore, the components will run only at optimal times. ATMOX focuses not only on energy efficiency and removing excess moisture but also on air quality. In order to be healthier, indoor air needs to be exchanged with fresh air.

Power Usage

The ATMOX controls use a low voltage 12V DC wire to power the fans. This means 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.

Assembled in USA from domestic and foreign parts. Includes 3-year limited product warranty.
