What is EPI?
EPI (Electrostatic Particle Ionization) System is a new environmental technology patented by BEI to improve air quality inside confinement livestock production buildings or other spaces. Using ionization to charge particles and remove them from the airspace is, however, not new. It is a proven concept. It works by emitting negative ions into the air. The ions capture and hold particles onto their interior surfaces, resulting in enhanced air quality in the space. In the livestock industry, where EPI Air is most frequently used, research shows that the outcome is improved animal productivity and livability.

What does the EPI Air System consist of?
The EPI Air System consists of 3 basic parts: Power supply, corona points and insulators. A power supply delivers ions under “high pressure” into the air through stainless steel corona points. The corona line is protected from the ground via insulators.

Where is the EPI Air System used?
The EPI Air System is most frequently used to reduce agricultural dust. Research is under way, but our hypotheses is that EPI Air improves animal health and livestock performance inside commercial layer, broiler, turkey and swine facilities. However the EPI Air System can be used in any confined space that has poor air quality, such as smoky manufacturing shops.

What type of electricity is required for installation of the EPI Air System?
Each EPI power supply uses about as much electricity as a 100 watt light bulb so it is extremely cost efficient to run. It requires a common 110-220 Volt, 50-60 Hz electric service. The power supply, controls, and monitoring equipment are housed in a sealed enclosure usually outside of the animal production area.

Why is dust collected on surfaces more acceptable then dust suspended in the air?
The EPI Air System requires a bit of a paradigm shift regarding room cleanliness, since a thick layer of dust will collect on surfaces of the barn. Dust collected on surfaces is superior to dust suspended in the air, even though it is more noticeable on the surface. Removing dust from the air enhances ventilation and presumably reduces stress on respiratory systems. Research shows EPI Air improves the overall performance and growth of livestock.

How should the dust collected on surfaces be cleaned?
When the animal production phase has been completed, the room can be cleaned as part of normal barn cleaning operations. When the EPI Air System is turned off, the components can be power washed or cleaned with a handheld leaf blower.

How is the EPI Air System installed?
BEI are primarily manufacturers of the EPI Air product, not installers. But, we do have some installation crews that may be available in your area if you need help with your first installation. We also have a detailed instruction manual and can train you on how to install the EPI Air System.

How long does it take to see results of the EPI System?
The results of installing the EPI Air System can typically be seen overnight. For instance, a swine nursery production room with the EPI Air System installed saw dramatic results after just a few hours.

Can the EPI System be retrofit into an existing structure?
Yes, the retrofit of existing structures has proven to be quite easily done. A two-person team of installers can complete the installation of a 40’ x 200’, swine production building in two days. If possible, installation in broiler, turkey and swine buildings should be scheduled between animal turns.

What is the warranty on the EPI System?
The life of the stainless steel components is indefinite and the power supply is warranted for two years, with an option for up to 5 years.  There is more information on the warranty at the bottom of the EPI Data & Certifications page.

Where is the EPI Air System made?
Hardware and materials used in the EPI Air System are American made. The EPI technology is built and assembled at BEI in Olivia, Minnesota, USA.

How long has air ionization been around?
Although the use of the patented EPI Air System for animal health and livestock performance is new technology, the concept of air ionization is not a new science. It was first used in 1842 and commercialized in 1907 to prevent sulfuric acid mist and lead oxide fumes from affecting a downwind California vineyard.

Where else is ionization used today?
Using ionization to charge particles and remove them from the airspace is not new. It is a proven concept. It has been used on smokestacks, in bars and restaurants, and in many other applications over the years. What is new is the ability to intensify the discharge of negative ions into the airspace in a manner that causes charged particles to collect on a large volume of grounded area.

How much does EPI cost?
The cost of installation of an EPI Air System varies greatly on the size of the barn and possible obstructions. Please contact us for a customized quote for the EPI System.
