are placed in series ahead of a particle filter in the sample line and all together are called the “Sample Line
Filter Assembly”.
Ammonia Trap Replacement
Observe the second (middle) ammonia trap in the assembly. When a color change (from blue to ‘wet’ dark
blue/aqua green) is noted, then the first ammonia trap is completely exhausted. Use the following procedure
to replace the ammonia trap:
1. Separate the first, completely exhausted ammonia trap from the 1/4" union connectors and discard.
2. Separate the second ammonia trap from the 1/4" union connectors and save.
3. Place and connect a new ammonia trap in the middle position.
4. Place the saved, second place ammonia trap, into the first-place position preserving the orientation of
the gas flow direction.
During continuous use, the exhausted media inside the trap is prevented from impairing (restricting) the flow
of gases through it. In some cases, when the Oxymax system is left idle for a week or more, the partially
exhausted media in the ammonia trap can “expand” and begin to restrict the gas flow. Although not
completely exhausted, the trap should be replaced to ensure proper gas flow.
3.2.5 Particle Filters
These 0.01micron microfiber filters are placed throughout the Oxymax system to prevent particles and debris
from entering and possibly impairing sensitive components. They are placed down-stream of animal cages in
front of the restrictors to prevent them from clogging. They are placed down-stream of the Filter Columns and
the ammonia traps to prevent dust particles from the filter media from entering the Universal Gas Conditioner.
Rarely do these particle filters exhibit notable visual signs of their use. Therefore, it is recommended to change
them at least once every five years.
