3.2 LUBRICATION GUIDE
See Figure 3-1. For best value and longest uninter-
rupted service, the LS20 Series compressors are
factory filled and tested with a long life lubricant.
Mixing of other lubricants within the compressor
unit will void all warranties!
If fluid change is required, follow Lubrication Guide
3.4 below.
“The Plastic Pipe Institute recommends against
the use of thermoplastic pipe to transport com-
pressed air or other compressed gases in
exposed above ground locations, e.g. in exposed
plant piping.” (I)
Sullube should not be used with PVC piping sys-
tems. It may affect the bond at cemented joints.
Certain other plastic materials may also be affect-
ed.
(I) Plastic Pipe Institute, Recommendation B,
Adopted January 19, 1972.
Maintenance of all other components is still recom-
mended as indicated in the Operator’s Manual.
For light-duty high-humidity service where con-
densed moisture and emulsification (mayonnaise)
may occur, the fluid change interval must be
reduced to 300 hours maximum. A non-detergent
fluid with rust, oxidation and foam inhibitors and
good water separation characteristics should be
used.
DO NOT MIX DIFFERENT TYPES OF FLUIDS.
Contamination of non-detergent mineral fluids with
traces of detergent motor fluids may lead to opera-
tional problems such as foaming, filter plugging, ori-
fice or line plugging.
Flush system when switching lubricant brands.
When ambient conditions exceed those noted or if
conditions warrant use of “extended” life lubricants
contact Sullair for recommendation.
3.3 APPLICATION GUIDE
Sullair encourages the user to participate in a fluid
analysis program with the fluid suppliers. This could
result in a fluid change interval differing from that
stated in the manual. Contact your Sullair dealer for
details.
