NOTE 1
Your enclosure is shipped with the prelter(s) attached to the inside of the enclosure. AirClean® Systems prelters
are ltrete electrostatic particulate lters with 65% efciency for particulate down to 0.5 microns in diameter (DOP
test). The prelter must be checked on a scheduled basis. Refer to the “MAINTENANCE” section of this manual.
NOTE 2
Your AirClean® Systems PowderSafe™ enclosure was shipped with the primary and permanent HEPA lters in-
stalled. The HEPA lters protect the operator from particulate but will not protect the operator from any fumes.
The HEPA lters must be changed on a scheduled basis. Refer to the “MAINTENANCE” section of this manual.
TECHNICAL SPECIFICATIONS

Type B Enclosure
AirClean® Systems Type B enclosures provide maximum operator protection during weighing
and lter change out. Variable Airow Volume Control ensures constant operator protection
from exposure to pharmaceutical compounds.
AirClean® Systems HEPASafe™ lter change technology allows for safe and easy change
of all contaminated lters, while under negative pressure. A permanent HEPA lter protects
the operator during primary HEPA lter change out. If the primary HEPA lter should ever be
compromised, it would also act as a permanent “nondisturbed” backup safety lter. The pre-
lter and primary HEPA lter are simply bagged out within the enclosure.
OVERVIEW
Independently tested and validated for personal protection from particulate.
Copies of these reports are available from AirClean® Systems upon request.

8
How PowderSafe™ Type B Works:
1. Air enters at “A” and is drawn in a laminar ow toward the rear plenum of the
enclosure while being mixed with contaminated air ”B”.
2. At “C” the contaminated air rst enters a roughing pre-lter before entering
the primary HEPA lter.
3. Air cleaned by the primary HEPA lter enters the permanent safety HEPA
lter at ”D”.
4. Clean air is returned to the room at “E”.

FILTER REPLACEMENT
HEPA Filters
The HEPA lter must be changed atlease every two years. See the “FILTER REPLACEMENT”
section of this manual for complete instructions.
The HEPA lter must be changed every two years or whenever it is clogged. The frequency with
which the lter must be changed depends upon usage. OSHA and the American Conference of
Government Industrial Hygienists (ACGIH) have published guidelines for Threshold Limit Values
(TLV’s) of exposure to chemicals and particulate. Local regulations may also contain specic TLV’s.
It is the express responsibility of the user to follow these regulations.
If the level of the substance being used exceeds the published TLV’s prior to the annual change
date, the HEPA lter must be changed. If the lter is changed prior to the annual date, it should be
changed every two years from this new date.
A.ToremovethespentACFHEPAlter:
1. Turn the unit on and make sure that the blower is running. The safety lter, located in the
top of the workstation, will protect you from any residual powders that might come off of the
