3.4 APPLICATION GUIDE
Sullair air compressors are supplied with Sullair AWF
which is a heavy duty multi-viscosity, all weather fluid
which provides an extended change interval when
compared to other fluids. Detergent motor oils (SAE
10W Class SE, SF, SG, or CD) can also be used.
Any of these oils are suitable under conditions where
severe oil oxidation can occur.
Water must be drained from the receiver tank
periodically. In high ambient temperature and
humidity conditions, condensed moisture can
emulsify with the oil forming a “milky” color. SAE
10W is especially prone to this condition. The fluid
should be changed if this condition develops. DO
NOT mix different fluids. Combinations of different
fluids can lead to operational problems such as
foaming, plugged filters, blocked orifices or lines.
When ambient conditions exceed the recommended
ranges, or if other conditions warrant the use of other
extended life lubricants, contact your local Sullair
representative for recommendations.
Sullair encourages users to participate in a fluid
analysis program. The analysis might indicate a need
for change intervals different from those
recommended in this manual. Sullair Corporation
offers a fluid analysis for Sullair AWF. Contact Sullair
for details.
D-A Lubricant® Company Inc. offers an analysis for
users of Sullair AWF. Contact your Sullair
representative for details.
