PPR piping can be used around compressor systems mainly for cooling-water and utility-water circuits, depending on the compressor manufacturer's specifications.
PPR piping applications with LG compressors
Cooling-water lines for water-cooled compressor systems
Chilled/cooling-water distribution
Condensate or drain lines, where chemically and thermally suitable
Utility-water connections around the compressor room
Compressed-air lines: generally not the preferred choice unless the specific PPR system is certified/rated for compressed air and the operating pressure and temperature are within its limits.
Important
For the actual compressed-air discharge from an LG compressor, use a piping material/system specifically approved for compressed air. Check the LG compressor's outlet pressure, temperature, connection size, and manufacturer recommendations before selecting PPR.
If you mean PPR piping for the compressed-air outlet of an LG compressor, �I can explain the complete piping layout and recommended fittings.
