CAUTION
!
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

be performed when the maintenance gauge shows

ELEMENT INSPECTION

1. Place a bright light inside the element to inspect
for damage or leak holes. Concentrated light will
shine through the element and disclose any
holes.
2. Inspect all gaskets and gasket contact surfaces
of the housing. Should faulty gaskets be evident,
correct the condition immediately.
3. If the clean element is to be stored for later use, it
must be stored in a clean container.

tighten all air inlet connections prior to resuming
operation.
