HEPA Filtration
XPert Bulk Powder Systems include HEPA filtration with a built-in
motorized impeller. XPert Bulk Powder Stations have HEPA filtration and
require an external blower. XPert Bulk Powder Enclosures may be
connected to multiple FilterMate Portable Exhausters to provide HEPA
filtration. All HEPA filters include a true Bag–In/Bag–Out filter change
system.

Waste Chute
The waste chute provides convenient trash and glove disposal without
removing hands from the enclosure. Hazardous waste bags need to be a
minimum of 8-1/2" wide x 11" long and may be obtained from many
different sources.

Four-Plex Electrical Box (J-Box)
The four-plex electrical box (J-Box) with four electrical outlets allows the
user to conveniently plug-in electrical cords from one location underneath
the work surface. See Figure 3-1.
Safety Precautions
Although the enclosure has been engineered to maintain optimum
operator safety, caution should always be used while working. Prior to
using the enclosure, check to make sure that the exhaust blower and
air monitor is operating correctly and that air is entering the enclosure
at its specified face velocity. The airflow monitor alerts the user if
there is a problem with airflow.
Use good work techniques at all times. Clean up spills immediately.
(Clean enclosure interior according to protocol).
Do not overload the work surface with equipment or work material. A
safe operation of the enclosure is based upon having proper airflow
through the structure. Do not place large, bulky objects directly on the
work surface. Instead, elevate the object 1/4" - 3/4" to allow a flow of
air under the object and into the rear baffle exhaust slots. Ensure the
equipment is level and secured in place.
Blocking large portions of the rear baffle will change the airflow
pattern in the enclosure causing turbulence and poor containment. (Do
not store containers or supplies against the rear baffle, as this will
affect airflow.)
Always work with your hands as far back in the enclosure as possible.
It is best to keep all powders, chemicals and equipment behind the
lower air foil of the enclosure.
Do not work with chemicals in this enclosure without the exhaust
system running.
