10.3 PUMP and PURGE Filter Changes
The AEROCET-380 PUMP FILTER and PURGE FILTER are the two filter cartridges located
on the side panel of the instrument. They can be removed by unscrewing the black
aluminum filter holders with a coin or flat head screwdriver using the slot in the face of the
holder. The expected lifetime of the two filters is greater than one year, but in heavy
particulate areas they may need to be replaced more often.
The 5 micron PUMP filter keeps any large particles from entering the sample pump. The
0.01 micron PURGE filter cleans the recirculated purge air which is used to keep the optics
clean during normal operation.
