10.5 Changing Air Filtration Cartridges
Correct filtering system component maintenance ensures that the quality of the air exiting the fill containment
station complies with the international breathing air standards.
The air filtration elements (cartridges) must be replaced at intervals calculated on the characteristics of the
environment in which the fill containment station is located. To calculate these intervals, refer to the table in
section 10.6.
The filter cartridge must be replaced before the air develops an unpleasant smell, when the litmus test paper
mounted inside the cartridge element turns white or a color other than blue.
The fill containment station comes standard with one (1) drying filter (SKU X96677) and one (1) breathing air
filter (SKU X96337). Do NOT use any substitute. Change filter elements every 40,000 cubic feet of air
pumped. If the fill containment station system is operated in high humidity and/or high temperature, filter
elements must be changed more often. See section 10.6 for details on filter element “life factors.”
CAUTION
A special breathing air filter element (containing a desiccant blend, activated carbon, and a
carbon monoxide catalyst) must be used when a diesel- or gasoline-powered compressor is
within proximity of the fill containment station.
•
Shut down the fill containment station system.
•
Open and leave open the bleed valve/s to vent all pressure from the circuit.
•
Use the wrench (a, Figure 6) to apply leverage on the screw heads (b) of the plug (c) and rotate
counterclockwise. If a filter wrench (SKU TL-033) is not available, a large screwdriver can be used to
unscrew the filter plug (1, Figure 5).
•
Remove the filter plug (2, Figure 5).
