KOSTGard® Compressor PAG 180
KOSTGard Compressor PAG 180 is a high performance synthetic gas compressor lubricant based on a quality polyalkylene glycol. It is designed for enclosed pattern gas compressors for hydrocarbon and chemical gases where the lubricant operates in a gas filled atmosphere. Under these conditions the gas is readily soluble in mineral oil lubricants which, on dilution, suffer a significant drop in viscosity and lubricant performance. This can be overcome by using KOSTGard Compressor PAG 180 in which gases are much less soluble.
KOSTGard Compressor PAG 180 is suitable for a wide range of gases including LPG, LNG, natural gas, landfill gas, propane, methane, butane, and ethane. It is also suitable for hydrocarbon gases such as ethylene, propylene, and butylenes as well as chemical gases like ammonia, vinyl chloride, and butadiene.
Ideally, compression gases should be dry, but this product will tolerate up to 4% water before hazing at 80°C, and has been evaluated for its corrosion resistance with 2.5% water. Common seal materials are unaffected by KOSTGard Compressor PAG 180 are Nitrile Rubber (NBR), Fluoro-Silicone or Vinyl-Methyl Polysiloxane (Q) are recommended. Ordinary industrial paints soften ion the presence of this product. Two-pack epoxy formulations are normally resistant. This product should never be mixed with mineral oil formulations as well as some other types of synthetics.
Reduced gas solubility leading to improved wear protection, lubricant life, and compressor efficiency
Reduced gas Excellent anti-wear and low friction properties
Wide temperature range of operation
Resistance to deposit formation under high temperatures
Excellent water separation
