1P2C
Traditional configuration for use with
powders, liquids and vapors, the 1P2C
column configuration positions the
HEPA filter immediately above the
base frame. Following the HEPA filter
is the junction frame, primary filter, fan
box and secondary filter on top. This
order is shown in Figure 8-20.
2C1P
Also utilized with powders, liquids and vapors, the 2C1P
configuration is intended for
cleanrooms. The 2C1P can be installed
in cleanrooms classified from ISO 1 up
to ISO 7 according to ISO 14644. The
HEPA is located at the very top of the
filtration column. This is shown in
Figure 8-21.
Note:
The 1P2C configuration is
preferred for dangerous particles or
powders because contaminated air is
always under negative pressure until
passing through the HEPA filter.
