C.2 Horizontal Flow Inlet
The P100 may be used for monitoring in a horizontal airflow environment (e.g., LAF Hood, HEPA Wall
Filtration Suite, etc.) with the aid of the P100 Horizontal Flow Inlet (P100.HRZINLT), depicted below.
The inlet is a simple two-piece design, the inlet, and an O-Ring. This design makes it easily
cleanable/sanitizable, by either chemical sanitants/disinfectants, or autoclave, if desired.
For use:
5) Simply set the horizontal inlet on top of a sanitized P100 100 LPM, or 28.3 LPM inlet cover, with the O-ring
evenly sitting at the rim of the opening.
6) Press the inlet down firmly and evenly, from the top of the inlet, until it seats with the P100 inlet cover.
7) Sanitize again if desired, purge the assembly for 30-60 seconds, and then perform sampling per Appendix A,
General Sampling with the P100.
NOTE: Once in place, the horizontal inlet can be removed with the inlet cover, for ease of changing
test plates.
