BioProtector systems use very high intensity, Advanced UV System (AUVS) technology to rapidly and
effectively destroy biological organisms in air. The UV intensity produced by the BioProtector is as much
as 100 times that produced by conventional low power UV germicidal systems. As a result, the technology
is uniquely effective. The sterilization effects obtained are significantly greater than those achievable
with conventional UV systems.
The BioProtector is integrated into an HVAC air duct system or manufacturing air supply system to kill
airborne microorganisms. The AUVS technology provides a means of increasing the UV intensity
produced by UV lamps by a large factor to achieve very high sterilization levels in air. Applications
include sterilizing air in pharmaceutical, medical and food manufacturing facilities to prevent product
contamination as well as providing protection against airborne organisms in hospital surgery, critical
care and isolation rooms.
The technology can also be used to protect personnel in buildings and shelters against biological threats
such as anthrax and smallpox and to kill other organisms such as SARS, bird flu virus, ordinary cold and
flu viruses, etc. The airflow pressure drop created by the BioProtector and the operating costs for the
systems are low.
The technology is very effective for destroying endospores that are highly resistant to UV. For example,
UV resistant endospore test organisms such as Bacillus subtilis are destroyed to greater than the 6‑log
level (>1 million times reduction). Vegetative microorganisms and viruses are significantly less resistant
to UV than these test organisms and are destroyed to an even higher degree.
The AUVS technology is based on an innovative UV enhancement or “photon multiplication” technology
that permits the use of relatively low power UV sources to achieve high microbial kill levels. This
technology permits the creation of very intense, highly uniform UV doses without increasing the input
power. The approach is analogous to that of a microwave or laser cavity. High amplification factors can be
obtained over the intensity that would be present without the reflective cavity. The UV enhancement
technology significantly reduces the power, size and cost of the system while increasing its performance
and reliability and decreasing maintenance costs.
