Designed to deal with Chemical and Biological dangers. The Chembio Airwash downdraft HEPA sorting station for use in secured rooms in conjunction with proper masks and gloves for maximum protection from possible threats. The ChemBio Airwash is a HEPA filtration system that creates a down-flow of air on a sorting surface, that leads directly into two HEPA filters. Possible particulate hazards such as Chemicals or Bio-Matter are forced into the HEPA filter. Each filter has 100 ft. of HEPA paper to allow maximum airflow. Can be ducted to create a negative pressure in the room (so any contaminates that do end up in the room, stay there to be drawn into the ChemBio Airwash). For maximum protection, items should be directed to a sealed room with a ChemBio Airwash system in use. The operator would use latex gloves and appropriate masking. Any items would be inspected and/or opened directly on the ChemBio Airwash's downdraft HEPA sorting surface. Amaircare(R)'s Dual-HEPA design, they each employ two high-efficiency motor/fans and up to 200 sq. ft. of HEPA for 99.97% removal efficiency of particulates 0.3 microns and larger. They also employ a variety of available V.O.C. (Volatile Organic Compounds) filters for removal of chemicals gases. Three-Stage Filtration Removes Particulates, V.O.C.'s and Odors. Easy-to-Change Filters Easy-access cover panels. Simply twist to remove, then install. Durable Metal Cabinets Greater protection for filters and internal components. Variable-Speed Control Adjust the airflow to suit your needs. No Harmful By-Products Amaircare(R)(TM) Air Filtration Systems do not produce toxins such as ozone. Three-Stage Filtration: Stage 1: Foam Pre-filterRemoves large particulates. Stage 2: HEPA filter 99.97% efficient @ 0.3 microns. Removes dust, pollen, bacteria, animal dander, attached viruses, cigarette smoke, radon daughters and more. Stage 3: V.O.C. filter Removes hazardous chemicals.
