Cabinet Pressure Plenums
The cabinets work area is surrounded by negative pressure and all external seals are under negative pressure. All
internal positive pressure plenum seals are surrounded by negative pressure plenums.
Design Details
Motor / blower capacity
A motor / blower’s capacity is measured by its ability to provide a nearly constant volume of air as resistance
increases because of filter loading. Verification by a simulated filter-loading test has established that your
SterilGARD
® III cabinet is capable of automatically handling 60% increase in pressure drop across the filter without
reducing total air delivery more than 10%. With the use of the manual speed control, a 180% increase in the pressure
drop across the filter can be handled.
Air balance adjustments
Air balancing can be done by either of the following methods. However, only a technician with proper training
and equipment should do it.
•
The cabinet speed controller adjusts for build voltage differences and filter loading. It controls the total air
volume being moved inside the cabinet.
•
The internal cabinet balancing damper compensates for down flow and exhaust imbalances due to
pressure drop differences between the filters when they are replaced.
Tested HEPA filters
All filters in the cabinet are scan-tested HEPA filters. They are 99.99% effective on particles of 0.3 micron size.
Each filter is leak checked after installation to assure that there are no leaks greater than 0.01% of the upstream
concentration.
Easy filter access
For convenience and ease of service, all filters are front accessible. The down flow and exhaust filters can be
removed through an access panel located behind the dress panels in the front of the cabinet. Qualified technicians
should only replace filters.
One-piece interior wall construction
The interior side and rear work area walls are constructed from a single piece of 16-gauge stainless steel. It has
7/16” [11.1mm] radius (rounded) corners to help prevent buildup of contaminants and aid in cleanup.
Front access high velocity air slots
At the intersection of both sidewalls and front access opening there are high velocity air slots. The purpose of the
slots is to capture any particulate traveling near the sidewalls and access opening.
