3.4 LUBRICATION GUIDE
Refer to Figure 3-1 for the fluid fill port location.
Sullair’s 4500P-7500 series compressors are filled
and tested at the factory with Sullube lubricant.
3.5 APPLICATION GUIDE
Sullair encourages its customers to participate in a
fluid analysis program with the fluid suppliers. In
some cases the analysis results suggest a fluid
change interval which differs from the User Manual.
Contact a Sullair representative for details.
