Rotary Screw Compressor Oils

Rotary Screw Compressor Oils & Lubricants

ProAirSupply supplies compressor oils and lubricants for rotary screw air compressors used in industrial compressed air systems. The correct lubricant helps provide lubrication, cooling, sealing, and protection for internal compressor components during operation.

Rotary screw compressors may require specific lubricant chemistries, viscosity grades, and service intervals depending on the compressor manufacturer, operating temperature, duty cycle, and application.

Looking for a specific rotary screw compressor oil? Enter the compressor manufacturer, model, OEM lubricant part number, or ISO viscosity grade in the ProAirSupply search bar to locate available replacement lubricants.

Why Rotary Screw Compressor Oil Is Important

Oil-injected rotary screw compressors rely on lubricant for several critical functions. The oil circulates through the compressor to lubricate moving components, remove heat, help seal internal clearances, and support reliable compressor operation.

• Lubrication: Helps reduce friction and wear on bearings, rotors, gears, and other moving components.
• Cooling: Helps carry heat away from the compression process.
• Sealing: Helps maintain sealing between internal compressor components during operation.
• Component protection: Helps protect lubricated surfaces from wear and contamination.
• Reliable operation: Proper lubricant selection helps support consistent compressor performance and service life.

Rotary Screw Compressor Lubricant Types

Rotary screw compressor oils are available in several lubricant chemistries and formulations. Depending on the compressor and application, these may include mineral, semi-synthetic, synthetic hydrocarbon, PAG, POE, and other specialty compressor lubricants.

Lubricant chemistry should not be changed without confirming compatibility with the compressor, seals, existing lubricant, and manufacturer recommendations.

Choosing the Correct Viscosity Grade

Rotary screw compressor oils are available in multiple ISO viscosity grades. The correct viscosity depends on compressor design, operating temperature, ambient conditions, and manufacturer specifications.

Two compressor oils with the same ISO viscosity grade may use different base stocks or additive systems and should not automatically be considered interchangeable.

Finding the Correct Rotary Screw Compressor Oil

The most reliable way to identify the correct lubricant is by using the compressor manufacturer, compressor model, OEM lubricant part number, and specified viscosity grade.

Rotary Screw Compressor Oil Maintenance

Compressor lubricant should be replaced according to the equipment manufacturer's recommended service interval. Operating temperature, compressor load, contamination, environmental conditions, and lubricant formulation can all affect oil life.

When performing an oil change, inspect related compressor maintenance components such as the oil filter, air intake filter, and air/oil separator where applicable.
