Airfiltronix has developed a cost-effective portable biohazard enclosure for opening small packages or mail. A negative pressure HEPA filtered blower ensures that no contaminated air can escape from the enclosure and gloveports on the front of the unit prevent the operator from coming in direct contact with potentially hazardous material. Self supporting hinged doors on the left and right sides allow packages and mail to be passed in and out of the enclosure. The front panel can be easily removed for access to the inside for cleaning. Floor is 1/2" thick, easy to clean, polyethylene. The HEPA filter captures particulate down to 0.3 microns in size, small enough to capture many bacteria, including Anthrax, which is 1 to 4 microns in size. An optional carbon filter may be added for additional protection. Unit is supplied with one pair fo 14" 15 mil neoprene gloves and one pair of 15 mil neoprene glovebox gloves (please state sizes required S,M,L).
