Moisture control in your crawlspace is the key to preventing mold and wood destroying fungi. We feature the ATMOX Crawlspace Ventilation System as an economical and effective alternative to Encapsulation.

ATMOX uses a combination of fans installed in the crawlspace vents and dehumidifiers. A controller is installed that measures wood moisture content, crawl space humidity, outside humidity and determines when air from the outside should be circulated through the crawlspace or the crawlspace should be closed off and use the dehumidifier. A control is mounted in a convenient location so you can monitor the status of your crawlspace at any time.
Homes used to be relatively simple in their design; rectangular in shape, with nothing to block air flow through the crawlspace. Crawlspace vents were spaced so many feet apart on all sides so that air could flow through and somewhat effectively help control moisture. But today’s homes are increasingly more complex with large garages, multiple garages, large porches on many sides and limited space to install vents. This creates large pockets of dead air in the crawlspace. The ATMOX system includes fans designed to hang from the floor joists and circulate the once dead air so that it can be processed by the dehumidifier or replaced with acceptable outside air.


Controlled ventilation for the entire crawlspace! Our ATMOX Crawlspace Ventilation System uses a series of intake and exhaust fans strategically placed in select crawlspace vents to ensure air circulates through the entire crawlspace. Vents that do not require fans are closed off. Sensors measuring dew points inside and outside the crawlspace feed the controller information where it determines whether to exchange air, dehumidify or simply keep the status quo. It’s a smart system that’s simple to operate.
