3.2 LUBRICATION GUIDE
Refer to Figure 3-1 for location of fluid fill port. For best
value and longest uninterrupted service, the 3700 Series
compressors are factory filled and tested with Sullube
lubricant.
If fluid change is required, follow Lubrication Change
Recommendations, Section 3.4.
Maintenance of all other components is still
recommended as indicated in the Operator’s Manual.
DO NOT MIX DIFFERENT TYPES OF FLUIDS.
Contamination of non-detergent mineral fluids with
traces of detergent motor fluids may lead to operational
problems such as foaming, filter plugging, orifice or line
plugging.
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.
CAUTION
Mixing of other lubricants within the
compressor unit will void all warranties.
