Field Controls Eliminator User manual

Eliminator Foundation Vent Fans were installed in homes
with high wood moisture content in the 28% to 30%
range. Over a thirty day period, the moisture content was
measured at weekly intervals. Homes with the Eliminator
installed saw a reduction of moisture levels to as low as
16% and 17%. A wood moisture level of 20% or less is
considered ideal. Homes without the Eliminator showed no
reduction in moisture content.
“The Eliminator performed well, even under severe moisture
problem conditions… the amount of air moved is sufficient to
correct the problems present.”

Eliminator®
Helps eliminate moisture, mold, and
radon gas from crawl spaces
Foundation Vent Fan

• Reduces moisture content and mold
potential in crawl spaces, floor joists,
flooring, and other support wood
• Circulates air in crawl space
• Removes radon gas
• Automatic operation
• Temperature or humidity activated
• Reduces potential for airborne mold
infiltration into home
• Reduces termite potential
The Eliminator Foundation Vent Fan 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. The
Eliminator attaches to virtually any standard
foundation vent. It is wired for automatic operation
when the temperature exceeds 50oF. An optional
de-humidistat activates the fan when humidity
exceeds the owner-determined setting (20%–80%)
in conjunction with the built-in temperature control.
The temperature control is shielded from the sun
to prevent false readings that could lead to costly
operation during cold weather.
Note: The de-humidistat is designed
to be installed remotely, so it can
be placed in the crawl space where
moisture is most likely to accumulate.

Facts about radon, mold, and moisture.
Mold
1. The Eliminator is attached to any standard foundation
vent, and then wired to a 120v source.
2. Optional de-humidistat is placed in center of crawl
space area.
3. When temperature in crawl space exceeds 50oF
and/or when humidity exceeds de-humidistat setting,
the Eliminator is engaged.
4. Moist air and radon gases are pulled from crawl
space and replaced with fresh, outside air.
5. When thermostat or de-humidistat are satisfied, the
Eliminator is deactivated.
Typical installation
Radon
Radon 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.
Mold
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.
Moisture
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 sub-
flooring. 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.
