I - FUNCTION AND DESCRIPTION OF THE BIOPROtect II JR CABINET The BIOPROtect II JR is a Class II Bio-Containment Enclosure designed to house laboratory robotics or large apparatus that would not ordinarily fit in a standard Class II Biological Safety Cabinet (BSC). Some important features of the BIOPROtect II JR include, vertical laminar airflow, a front access opening, as well as supply & exhaust HEPA filters. The unit is designed to protect not only the environment and the people using the cabinet, but also the product within from airborne contaminants. The BIOPROtect II JR can be configured to vent three different ways. Vent to the room, Vent to a Canopy Exhaust Connection (C.E.C.) via a house exhaust system or, Vent to a Hard Exhaust Connection (H.E.C.) via a house exhaust system. Although your unit has passed a microbiological test, a modification of NSF/ANSI standard-49-2002e, the BIOPROtect II JR is not currently listed with the NSF. Airflow Inside the BIOPROtect II JR Cabinet Figure 1 shows the name and location of component parts and the typical airflow pattern of the BIOPROtect II JR The stainless steel metal diffuser (1) just below the supply HEPA (High Efficiency Particulate Air) filter assures that the work area is bathed in HEPA filtered air. The supply air stream splits so that some is directed into the front grille (2) and the balance is pulled into the perforated grilles on the rear wall (3). On a flat table top, in the absence of any obstacles, the air should split roughly in the center of the table. Because the cabinet must take in air to replace the air which is expelled through the exhaust filter, the same quantity of room air enters the cabinet through the eight inch front access opening. The flow of the intake air provides the personnel protection (containment) aspect of the cabinet. The front grille of the cabinet is integral to the large hinged door. This door, as well as the side and rear walls, are maintained under a negative pressure. Air is drawn from the front intake grille, into the hollow door, and into the right side wall. In this manner the outside air that is drawn into the cabinet as intake is not allowed to penetrate the table top area of the cabinet. Any and all contaminated air that is captured in the cabinet’s negative pressure plenums (front door, side walls, rear walls or upper plenum) is pulled into the cabinet’s blower (4). The blower discharges into a steel box that is a common plenum for the supply and exhaust HEPA filters (5). In this manner, all the air that is handled by the cabinet is HEPA filtered. The BIOPROtect II JR will exhaust a quantity of air (6) equal to that received at the front intake grille. If a leak should occur in a contaminated pressure plenum the negative pressure will create suction and pull air in, not allowing it to escape into the laboratory. If there is a leak from the positive pressure plenum, the surrounding negative pressure area will recapture the contaminated air and recirculate it through a HEPA filter. http://solid/prereleased/prereleased/STAN.

Access to the Work Area Figure 1 Typical section with airflow visualization arrows The BIOPROtect II JR is provided with three modes of access to the work area; via the large hinged door that can be opened to access the entire work area, the hinged viewscreen (providing access to the work surface) or from the 8” x 42” access (sash) opening between the bottom of the closed viewscreen and the air intake grate. The primary means of access must be through the 8” sash opening. This is the only means of access that will ensure the user protection from contaminants within the enclosure. The operator is only protected from airborne particulate when the large front door and the hinged viewscreen is closed and secured to provide an 8” x 42” access (sash) opening For easy set-up of equipment in the work area, the BIOPROtect II JR has one large door that exposes the entire work area from floor to ceiling to an area of 51.5” wide x 68” tall. http://solid/prereleased/prereleased/STAN.
