Field Controls Eliminator Foundation Vent Fan
The Field Controls Eliminator Foundation Vent Fan is designed to circulate fresh air into crawlspaces. This fresh air will help to remove moisture, which will decrease mold and fungus growth and dry rot.
Mount the Eliminator Foundation Vent Fan on a new or existing crawl space vent. Installed on the fan is a temperature control, which turns on the fan at 50 degrees. Additionally an optional de-humidistat can be purchased and installed. When the de-humidistat is used it will activate the fan at selected humidity level. (Contact Positive Energy for more information and availability).
This foundation vent operates at 135 CFM and can cover an area of about 1000 sq/ft. So most standard sized ranch homes should be covered.
Other Crawl space fans on the market cost over $100 and some do not include controls. So be sure to shop around.
The Eliminator EL-1 is listed as a potential radon mitigator.
