Crawl Space Ventilation Fans – Internal Mount – Intake Fan 

These crawl space ventilation fans are unique and designed for vent openings that fall between joists. This is typical in West Coast or California construction. ATMOX systems are adaptable to different crawl spaces in various geographic regions such as these. You can mount these fans inside the crawl space in the vent openings between the floor joists. A benefit to internal mounting is allowing for unique or aesthetic vent covers to remain untouched. If necessary, you can mount crawl space fans with a cover from outside when space is particularly tight. Also, a grill can be provided to cover vent openings, if needed.

These intake fans 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 system will run at optimal times with the use of the ACE Controller. All ATMOX products are designed with an emphasis on energy efficiency because moisture control systems should be effective and inexpensive to operate.

With the ATMOX controls, a low voltage 12V DC wire gets power to 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.
