Gray Foam Filters
•
The gray foam filters used inside the absorber column (top and bottom) will wear over time and
should be inspected regularly and replaced when torn or reduced in size. The foam must be of an
open celled type, such as packing foam. The foam filters at the bottom of each column will likely
require more frequent changes versus the upper foam filters.
Absorber Filters
•
Each absorber end cap contains a white plastic filter disk. Generally these do not need to be
replaced but should be checked periodically. However, they must be present to prevent any of the
column contents being drawn with the gas stream causing damage to the instrument.
End Cap “O” Rings
•
Each end cap has two “O” rings, one that seals inside the plastic column and another that seals
at the manifold. All “O” Rings on the absorber column should periodically (every couple of weeks)
receive a slight smear of silicone grease to aid ease of fitting, improve the seal and extend the life
of the “O” rings and to keep them from cracking or breaking. Once sealed, end fittings should be
checked to ensure that the O-rings are seated correctly in their groove and that they are not
trapped or pinched resulting in system leaks.
