ATMOX Crawl Space Intake Fan – 225 CFM – Multi-Mount

The design of the crawl space intake fan allows for a variety of configurations in an attic or crawl space. The mounting plates and accessories are all sold separately for customization. For example, two fans can be mounted on a double flat plate to increase the power to 450 CFM. Another option, is to add ducting to a fan in order to direct air to the hard-to-reach areas. In an attic, these fans can be used in soffits.

Crawl Space

In the crawl space, ATMOX offers the best moisture control system through the use of smart ventilation and/or dehumidification. 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 ATMOX components will run only at optimal times.


In an attic, the APEX Controller and fans work to control moisture and heat reduction through attic ventilation. 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 house 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 and crawl space 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.
