Air Compressor Lubricants and Oils

The appropriate oil depends on the compressor manufacturer, model, lubricant specification, viscosity grade, and operating environment. US Compressor offers OEM-equivalent products for brands including Quincy, Atlas Copco, Champion, Curtis, Sullair, Kaeser, Ingersoll Rand, Mobil, Anderol, Royal Purple, and others. Use the cross-reference guidance or contact technical support before changing lubricant types.

ISO 68 and ISO 100 identify different viscosity grades. ISO 100 oil is thicker than ISO 68 at the applicable reference temperature. The correct grade depends on the compressor design, OEM specification, operating temperature, and application. Do not substitute one grade for another without confirming compatibility with the equipment documentation or a qualified technical resource.

Yes. The range includes products specifically identified for rotary screw compressors, including synthetic, semi-synthetic, PAG, PAO, diester, silicone, mineral, and food-grade formulations. Compatibility varies by product and compressor model, so confirm the OEM lubricant, viscosity grade, formulation, and any pour-over or flushing requirements before servicing the machine.

Yes. Product information identifies lubricants for reciprocating, piston, and vane compressors, as well as rotary screw equipment. Available viscosity options vary by product and application. Selection should be based on the compressor manufacturer’s specification, operating conditions, existing lubricant, and required protection against oxidation, wear, rust, corrosion, carbon, or varnish.

Yes. Several products are identified as NSF H1 or as meeting H1 requirements for incidental food contact. These include food-grade options for rotary screw compressors and applications in food and beverage processing. H1 status does not remove the need to follow the equipment manufacturer’s maintenance instructions and applicable site procedures.

Yes. US Compressor provides lubricant selection guidance, cross-reference support, technical assistance, and free oil analysis. The catalogue includes replacement products for numerous OEM and lubricant brands. Provide the compressor make and model, current lubricant name, viscosity, application, and any operating or compliance requirements so compatibility can be reviewed accurately.
