8.4 COMPRESSOR LUbRICANTS
8.4.1 FACTORY FILL
The compressor is filled with the appropriate amount of lubricant at the Factory before shipment. Palasyn 45
is the standard lubricant used at the Factory to fill UD-Series compressors. A decal, typically located on the
sump tank, indicates the specific lubricant type needed for compressor maintenance. Other lubricants are
available as an optional fill upon request.
8.4.2 OIL COOLANT LIFE VS. OPERATING TEMPERATURE
Fluid Life vs. Operating Temperature is only a guideline for typical oil life if temperature is the only variable
to be considered.
See Figure 8-1. Many variables affect the oil life, such as environmental impact from various
gases, dust and dirt, compressor short cycling, etc.

Sullivan-Palatek recommends oil sampling as the best guide for your fluid change interval. Changing
fluid once a year may not be adequate or it can be excessive. For this reason an hourly service on lubricants
is merely a guide. Please consult your factory-trained servicing Distributor for questions concerning your
lubricant life and Sullivan-Palatek’s lubricant sampling program. See 6.6 Oil Sample for Analysis on page 49
for additional information.
