    • SIMPLE INSTALLATION: Installs easily
    • SAFE: Keep your home, office, or building safe from rotting support columns, joists, floors, and beam supports
    • PERFORMANCE: Helps eliminate radon gas from your home or building by circulating fresh air

Features of the Eliminator Crawl Space Vent Fan

The Eliminator Crawl Space Vent Fan (EL-1) is a motorized fan designed to circulate fresh air in a home or building crawl space to eliminate cancer-causing radon gas and reduce moisture that can lead to mold formation and termite infestation. It is wired for automatic operation when the temperature exceeds 50°F. An optional de-humidistat (EDH-1) activated the fan when the humidity exceeds the owner-determined setting (20% to 80%) in conjunction with the built-in temperature control.

What is a Crawl Space Vent Fan?

What is a crawl space fan? A crawl space is designed to circulate fresh outdoor air underneath homes and porches. Excessive humidity levels in crawl spaces can cause premature rotting of support columns, joists, floors and beam supports. Humidity can promote fungus growth and increased termite activity. Humidity may also cause plumbing failures due to rust and corrosion. Constant operation of a crawl space fan also helps vent radon gases, treated wood off-gassing and other odors that can migrate into living areas.

What is Radon Gas?

Radon gas is a radioactive gas that is considered to be a health hazard affecting indoor air quality worldwide. Radon gas is the second most common cause of lung cancer in the United States. One in fifteen homes in the U.S. has a high level of radon.

According to a study by the Mayo Clinic, nearly all chronic sinus infections are a result of mold. Since up to 40% of the air we breathe in the home can come from the crawl space, mold in the crawl space means
mold in the home. The EPA recommends to keep humidity levels in the crawl space to 40%–50% to reduce the likelihood of mold formation.

Excess moisture in a crawl space can have serious consequences. Not only can it lead to mold formation, it also increases termite potential and can increase the  potential for rot in floor joists, cross members, and subflooring. Moisture level in wood should be less than 20%. In high humidity areas, that number can easily exceed 30%. To maintain safe moisture levels, experts recommend a plastic moisture barrier on the ground in combination with a vent fan such as the Eliminator.
