Sullair Industrial Air Compressor 5507V/A

CAUTION: Do not mix different types of lubricants. Mixing lubricants can cause malfunctions or compressor damage and will void the compressor’s warranty.

CAUTION: Contamination of compressor fluids with mineral oil or other fluids can cause foaming, filter plugging, or orifice line obstruction.

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 that differs from the User Manual. Contact a Sullair representative for details.

When performing a fluid change or topping off the fill, the proper level should be at half of the sight glass, with the machine off.

Mixing, changing, or adding other lubricants within the compressor unit may void the air-end warranty.

Change the compressor fluid using instructions shown in the 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.
