Compressor Oil vs Hydraulic Oil
High-level guidance for distinguishing compressor oils from hydraulic oils, focused on additive systems, air release, and oxidation stability.
This page lists neutral selection inputs. Confirm equipment manufacturer specifications before selecting a lubricant.
Operating Conditions
| Operating Parameter | Typical Range/Value |
|---|---|
| System | Rotary screw/reciprocating compressor vs hydraulic system |
| Temperature | Compressor discharge temperatures can be high |
| Air Exposure | Compressor oils see high air entrainment |
Required Lubricant Properties
| Required Property | Specification |
|---|---|
| Oxidation Stability | Resists varnish/sludge at elevated temperature |
| Air Release | Releases entrained air quickly |
| Additive Suitability | Correct additive package for the equipment type |
