Usage and Maintenance Notes
- Do Not Mix: Avoid mixing with other oils to prevent chemical reactions and performance loss.
- Storage: Seal containers after use; prevent contamination from water or dust.
- Compatibility Test: Conduct compatibility tests with rubber, plastics, and paints before use.
- Oil Replacement (Reciprocating Piston Compressors):
- Drain old oil while warm, clean or replace filters, flush crankcase.
- Add new oil of the same viscosity grade. Clean cylinder valves, air passages, condensers, and separators of carbon deposits.
- During initial operation, frequently monitor and replace running-in oil after 150–250 hours.
Compressor Lubrication Guidelines
- Reciprocating Compressors:
- Internal lubrication for cylinder, seals, and anti-rust; oil exits with gas without circulation.
- External lubrication for moving parts and cooling.
- Rotary Compressors:
- Dry type: lubricates only bearings and gears.
- Oil-injected: oil injected into compression chamber, separated and recirculated; requires special rotary compressor oil.
