Now more than ever air filtration systems are being used to counter chemical, biological, radiological and nuclear (CBRN) threats. These filtration systems are increasingly used world-wide to purify ventilation air in government and important commercial buildings, on navy ships, in shelters, and on vehicles, allowing critical operations to continue in the event of an airborne release. HDT is a world leader in the design, installation, testing and maintenance of air filtration and collective protection (ColPro) systems for CBRN defense.

To provide effective protection against military-grade CBRN agents such as those used by terrorist organizations, a system must perform to a much higher degree than any commercially available filter on the market today. Most commercial filtration systems—which typically utilize free-standing indoor air purifiers or filtration units—vary widely in configuration and effectiveness, relying on a High Efficiency Particulate Air (HEPA) filter designed for the removal of microbiological aerosols such as bacteria, fungi and viruses and a commercial-grade activated carbon filter for the removal of chemical gas or vapor agents. These filter systems are not designed for, nor are they capable of, protecting against military-grade toxic agents.

To meet this need, HDT has taken the same proven designs originally developed for the military and incorporated the technology into its complete line of commercial CBRN filtration systems. These systems are designed with high-efficiency HEPA filters and specially designed carbon adsorber filters containing ASZM-TEDA impregnated activated carbon adsorption media designed to remove a wide variety of military-grade toxins.

HDT continues to develop new CBRN filter designs that can protect not only against military-grade toxic agents but also against a wide array of Toxic Industrial Chemicals (TICs), addressing the threat from either an intentional or accidental release. Systems incorporating this next generation of filters can be installed to help protect schools, commercial buildings or other structures located in the path of a potential TIC release.
