 ATMOX Attic Exhaust Fan – 225 CFM – Multi-Mount

These powerful attic fans bring in outside air when conditions are met by the ATMOX controller. This fresh outside air will effectively reduce and remove heat in the hot attic. As a result, this will improve the air quality of an attic and the living space in the rest of the house. The design of the attic exhaust fan allows for a variety of setups in attics. The attic fan can be used to exhaust out a ridge vent or gable. The single mount plate comes with the fan. All other mounting options for double plates, 4/12 ridge vents, 8/12 ridge vents, roof caps or gooseneck roof caps are sold separately for customization.


In an attic, the APEX Controller and attic exhaust fans work to control moisture and heat reduction through attic ventilation. However, the ATMOX setup is not just a set of venting fans in your attic space. It’s a smart solution using decades of research and science to bring the best system to your attic.

In addition, ATMOX is adaptable to different attics that may vary by construction or climate. In many regions attic spaces tend to be very hot during the summer months. Attic temperatures can actually be extremely high. This heat may cause damage to roof shingles and lead to an overuse of HVAC systems. With use of the APEX Controller and fans, your attic will benefit from heat reduction.

In the winter months, the outside air is generally drier. However, attics are still at risk for moisture issues. These issues can lead to issues of mold or wood rot. The warm moist air that forms inside the living area escapes to the attic. If that moisture gets trapped in the attic, it can lead to moisture on the cold surfaces. Also, in areas with heavy snowfall, ice dam issues can lead to major moisture and water damage. The ATMOX APEX Controller has an optional Snow Mode to assist with ice dam mitigation by removing warm air from the attic.

While there are climate differences throughout the regions of the US, your attic will benefit from the ATMOX system. Our regional map can help you with the best solution for your region.

Power Usage

The ATMOX Controls use a low voltage 12V DC wire to power the fans. As a result, 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. Therefore, in this setup the fans will run continuously.

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