Hospitals and medical centers, government buildings, office complexes, and other facilities are vulnerable to bio-terrorism attacks. Biological agents such as anthrax, and chemical agents such as sarin gas or ricin, are particular concerns. Our Anti-Terrorism Laser Air Sterilization System contains a laser-generated, high-energy field that incinerates biological and chemical agents, and other substances, as they pass through the special treatment zone. This system is completely self-contained and adapts easily to any HVAC system.
