OCP Oil PAG/POE 8000-46
PAG/POE compressor fluid for machines already running on a polyglycol or ester coolant. Varnish-free, 8,000 to 10,000 hours.
8000-46
OCP Oil PAG/POE 8000-46 is a long-life compressor lubricant built on a synergistic blend of PAG (polyalkylene glycol) and POE (polyol ester) base oils, for rotary screw and centrifugal air compressors that run hot for long periods and on long drain intervals.
It is the service fill for compressors already running on a polyglycol or ester coolant. PAG/POE fluids are not compatible with mineral oil or PAO based lubricants, so a compressor coming from those needs a controlled changeover; ask us before switching. For a drop-in alternative that mixes with any hydrocarbon oil, see OCP Oil Prime 12000-46.
Efficiency
Higher thermal conductivity for a cooler running compressor, very low carry-over, and lubricity that extends compressor life.
Compatibility
The natural service fill where a PAG/POE coolant is already in use. Good compatibility with medium and high nitrile and Viton seals; not compatible with mineral oil or PAO based lubricants, and polyglycols attack some conventional paints, so epoxy-painted reservoirs are recommended.
Protection
Varnish-free operation that also dissolves varnish left by earlier lubricants, with corrosion protection and resistance to thermo-oxidative degradation. Blended with readily biodegradable base stocks.
