A device in which exhaust fluid from a facility or equipment for treating biologically active material is heated to a temperature of at least 400 � C. to kill or denature hazardous agents, and conveyed through a metal filter with no more than 0.1μm pore size, which is heated, preferably by the fluid, to essentially the same temperature. The relevant temperature is maintained during operation in both the fluid and the filter. Since the filter is dimensioned to trap microbial agents like bacteria and viruses and the temperature of the filter surfaces is sufficient for sterilization, microbial agents are bound to come into contact with said surfaces and a very high degree of sterilization certainty is reached. The filter is welded to the device body to provide a seamless structure. Heating and filtration are both alone sufficient for removing biohazardous agents, so the device provides double security. |
