The AAF Bag In/Bag Out Access filter system is safe, simple, reliable and utilizes a method for removing contaminated particulate filters and/or gases in hazardous environments. With this system, maintenance personnel are
protected from direct contact with the interior of the housing and hazardous contaminants during filter change-out and testing. Each removal bag is cinched to a collar inside the housing door to prevent any leakage of contaminants during filter replacement. Similarly, new filters are installed with the aid of a protective plastic bag. At no time during the change-out is the external atmosphere exposed to contamination from within the filter housing.
