Lubricant selection inputs for lubricated air compressor systems (rotary screw/reciprocating), including varnish control and water separation.
This page lists neutral selection inputs. Confirm equipment manufacturer specifications before selecting a lubricant.
Operating Conditions
| Operating Parameter | Typical Range/Value |
|---|---|
| Temperature | Elevated discharge temperatures possible; oxidation stability matters |
| Water | Condensation and water separation behavior important |
| Duty Cycle | Continuous duty common for screw compressors |
| Compatibility | Seal compatibility and OEM approval requirements may apply |
Required Lubricant Properties
| Required Property | Specification |
|---|---|
| Oxidation Stability | High; resist varnish/sludge formation |
| Demulsibility | Good water separation where required |
| Viscosity Grade | Per OEM; commonly ISO VG 32/46/68 depending on design |
| Rust/Corrosion Protection | Required in humid environments |
