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 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 the 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).
• Remove the first cartridge (3, Figure 5) and the second cartridge; replace both with new cartridge elements. Place pressure on each cartridge (4, Figure 5) to seat the element fully into the canister. Replace the O-ring (e, Figure 6) on plug (c) every time the filter is changed.
• Reinstall the cap to the canister by rotating clockwise and tightening it with a screwdriver or cap wrench.
• There are sealing O-rings (e-f, Figure 6) on the plug and the filter cartridge. If these O-rings deteriorate, the air is released via the venting hole (g).
• If you notice any venting from this hole replaces the O-rings. When replacing the O-rings observe the precautions described at the start of the section.
• Close the bleed valve/s.

DANGER
Do not carry out these tasks if the fill containment station has just shut down and is hot; wait for the fill containment station to cool. All maintenance work must be carried out with the fill containment station OFF and the power supply lead unplugged from the wall socket.
WARNING
Be sure that all pressure has been relieved from the system prior to opening any filtration canister. Failure to vent pressure from the system prior to opening the canister can
lead to serious personal injury or death. Difficulty turning the filter cap may indicate there still is pressure in the filter canister.
CAUTION
If the fill containment station is in an area where there is high humidity and high heat, the life of all filtration elements may be as little as 35% of the rated operating capacity. Check the filled containment station manual and an appendix for details on Filter Element Life Factors.
10.6 Temperature Effect on Filter Life
This Filter Replacement Frequency Calculation Table is based on the total hours of fill containment station runtime. The table values are based on the pressure maintenance valve calibrated to 2900 psi (200 bar). Higher pressures will affect overall performance.
