6. Restart compressor and check for leaks.
To minimize the possibility of filter element rup-
ture, it is important that ONLY replacement ele-
ments identified with the Sullair name, logo and
appropriate part number be used and that substi-
tuted elements not be used, due to the fact that
such filters may have inadequate or questionable
working pressure ratings.
AIR FILTER MAINTENANCE
Refer to Figure 7-2
75HP/ 45-56KW models, and Figure
100HP/ 75KW model. Air filter maintenance should
be performed when the maintenance gauge shows
red with the compressor running full load, or once a
year, whichever comes first. If the filter needs to be
replaced, order replacement elements. Below you

elements.
