Small TFA and Temporary SheltersHunter offers several CBRN collective protection filter systems for TFA and other smaller applications. Hunter’s H100GPFU and H200GPFU (Gas/Particulate Filter Unit) collective protection systems can be designed into a TFA to provide up to 200 CFM of clean breathalbe air. Applications for these units would include TFAs for shelter in place, as well as command and control rooms or mobile vans used by first responders or emergency teams operating from enclosed vehicles within a contaminated area.
In both cases, Hunter ASZM-TEDA carbon absorption filters can maintain efficiency greater than 99.999% for up to three years of continuous use if not exposed to toxic agents. Hunter HEPA filters maintain efficiency for an average of two to five years depending on operating conditions. What's more, Hunter designs filter systems for both continuous duty and standby operation. The latter are activated only when there is a greater likelihood of a CBRN incident. For more detailed description on how to incorporate these units into your TFA please consult our design guide. A free copy will be sent to you on CD or you may order a pre-printed report and binder.
