Air Purification System

The Whole House Solution

Field Controls offers a complete line of UV-Aire products
for any home or business, with a variety of duct-mounted
UV-Aire models designed for forced-air heating and
cooling systems. UV-Aire germicidal lamps continuously
attack airborne mold, bacteria and viruses as they circulate
through your ductwork.

For homes and businesses without a forced-air system,
Field Controls manufactures two portable models. The
portable models combine the purifying power of UV
with high efficiency filtration and carbon filtration to
reduce dust, pollen, odors, and Volatile Organic
Compounds (VOCs).

The UV-500C and UV-1500C provide concentrated UV
germicidal protection in bedrooms, living rooms, and
offices… where it’s needed most. Each portable model
utilizes a motorized fan with multi-speed control to quietly
and efficiently circulate and treat indoor air. The UV-500C
is recommended for rooms up to 500 square feet, while
the UV-1500C can purify areas up to 1500 square feet.

For those who require extra protection, the 24/7 benefits of
the in-duct models can be enhanced with the concentrated
power of the portable units. The combined use of portable
and in-duct models is an extremely effective whole house
solution. This approach is recommended for anyone with
allergies, respiratory illnesses such as asthma, or a
compromised immune system*.

With 40-75 air changes per day during normal operation,
the cumulative effect of UV-Aire in-duct models reduces
airborne bacterial concentrations. UV-Aire works in
combination with a quality filter. An upgraded media filter

(MERV 8 or higher) is recommended. Filters trap larger
particles, allowing microscopic organisms to pass through
where they are zapped in the UV-Aire treatment zone.

Indoor Air: High Concentrations of
Biological Contaminants

With tighter building construction in recent years, the
quality of indoor air has declined dramatically.

The air circulating in the ductwork of the average
home or office can be concentrated with contaminants
including molds, bacteria, viruses, and dust mites.
We fill our lungs up to 20,000 times each day. Over
time, these contaminants can cause inflammation of
the mucous membranes, upper respiratory problems,
asthmatic conditions, headaches, and flu-like symptoms.

Filtering systems offer little or no help because these
airborne contaminants either pass through the filter or
simply collect on the filter medium, creating a breeding
ground. Now, with the UV-Aire

®

Air Purifying System, a
solution is available to directly address the problems
associated with poor indoor air quality.

The Sun: Nature’s Outdoor Air Purifier

For years, scientists have known that one of the most
effective air purifiers is natural sunlight. Not the light we
see when we look out the window, but the invisible “C”
band, ultraviolet rays that make up part of the sun’s light
spectrum. The sun’s UV-C rays act as a natural outdoor
air purification system, inhibiting the growth and
reproduction of bacteria, viruses, fungi, molds, and dust
mites. However, this natural process does not occur
indoors. Ultraviolet radiation (UV-C) replicates the natural
outdoor purification system of the sun by destroying the
illness and disease-causing microbes living and
multiplying in indoor air. In combination with a quality
filter, it is the most effective way to reduce airborne
contaminants and the health risks they represent.

Eliminate Moisture Problems

Excessive moisture under a house can

contribute to air pollution inside the

house. The Eliminator®Foundation Vent
Fan is a motorized fan designed for circulating outside
air through the crawl space of a structure to reduce
moisture and moisture-related problems. In addition to
dry rot, fungus growth and increasing termite potential,
excessive moisture can generate mold. Mold and mold
spores can infiltrate the living space as well as the
HVAC system, causing problems for the inhabitants.

With the Eliminator, air changes are increased
dramatically for better moisture removal and control.
The EL-1 is designed to be mounted to a crawl space
vent. It operates off a temperature switch which
activates the motor at or above 50°F. An optional,
adjustable de-humidistat can be used to activate the
unit at varying levels of relative humidity. This optional
control can be wired in place of, or in series with, the
standard temperature switch.

Facts About Indoor Air

Facts About UV

• According to the Environmental Protection Agency,
the air in homes can be up to 100 times more
polluted than outdoor air.

1

• The National Academy of Sciences Institute of
Medicine reports that exposure to indoor pollutants
is a key contributor to the asthma problems of
this nation.

2

• Most allergy and asthma sources are passed from
person to person through the air.

• The air in a single room can contain hundreds of
thousands of infectious bacteria, viruses, fungal
spores, and contaminants, which can only be seen
with a microscope.

• Health effects may show up immediately, or after
years of exposure to poor indoor air quality. These
symptoms include some respiratory diseases, heart
disease, and cancer. They may be severely
debilitating or fatal.

• The disinfection of medical equipment using UV
has been a common and reliable practice.

• UV disinfection has been determined to be
adequate for inactivating bacteria and viruses.

• The germicidal effects of UV light cause

• “...ultraviolet radiation, properly integrated with
heating, ventilating, and air conditioning systems,
shows the most promise as a widely applicable
means of air disinfection.” Richard Riley, M.D.

* The UV-V wavelength generates ozone. According to the
Environmental Protection Agency, ozone can be harmful to your
health. When inhaled, ozone can damage the lungs. Relatively
low amounts of ozone can cause chest pain, coughing,
shortness of breath, and throat irritation. Ozone can also
compromise your ability to fight respiratory infections.

All UV-Aire lamps are coated to block this wavelength.
