Required maintenance for the Balston Nitrogen Generation System consists of changing the prefilter
and final filter cartridges (annually), changing the galvanic cell in the oxygen analyzer (annually),
checking the performance of the system, and calibrating the oxygen analyzer. The recommended
service schedule and replacement part numbers are outlined at the end of this section. The calibra-
tion procedure for the oxygen analyzer is outlined on page 6. The analyzer should be calibrated on
a regular basis, as dictated by the application.
Changing filter cartridges more frequently will translate into direct energy savings and reduced
operating costs. Annual electricity costs to operate a typical 100 HP compressor can be as high as
$50,000. Pressure drop in the system adds to this expense. A system operating at 100 psig that is
exeriencing a 2 psig pressure drop through a filter, requires an additional 1% in operating energy
costs or approximately $500.00+ per year.
Replacement prefilter cartridges, final membrane filter cartridges, and galvanic cells may be ordered
through your local representative. For convenience, these replacement items have been packaged
into a maintenance kit for each generator. Maintenance Kits provide a 6 month supply of filtration
replacement components.
The only tools required to change the prefilter cartridges and the final membrane filter cartridge is a
Phillips head screwdriver. All filter housings which require routine service are easily accessible
when the front filtration access panel is opened. (Remove the four corner screws.) The two coalesc-
ing prefilters are Balston 2002N-1B1-DX and 2002N-1B1-BX filter assemblies (see Figure 7). Re-
place these filter cartridges with Balston 100-12-DX and 100-12-BX filter cartridges. When replacing
the prefilter cartridges, be sure to install the proper grade filter in the proper housing (the housings
are labeled). The final membrane filter is a Balston 2002N-0A0-95 filter assembly. Replace this
membrane filter cartridge with a Balston Grade GS 100-12-95 membrane filter cartridge.
The filter cartridges in the filter assemblies are removed by: twisting the filter bowl clockwise 1/8 of a
turn while pushing up gently, lowering the filter bowl away from the filter head, and unscrewing the
element retainer from the base of the cartridge. Insert the new filter cartridge and reassemble the
housing in reverse order.
The time required to service all three stages of filtration is less than 15 minutes.
