Compressor oils and vacuum-pump oils are used to:
• Lubricate shaft seals, bearings, screws.
• Remove heat generated by compression.
• Remove contaminants via the filtration system.
• Protect against corrosion.
• Form seals between screws and housings to prevent compressed gases from escaping.
• Lubricate and remove heat
Overheating of compressor systems can cause compressor oil to degrade and form residues that cause the entire system to work harder (stresses, fatigue).
Synthetic lubricants resist these effects. Although conventional mineral oils are less expensive, they have an estimated service life of between 500 and 1,500 hours.
Synthetic oils generally have a higher service life, which is estimated to last between 4,000 and 8,000 hours.
Used to lubricate vacuum pumps and air compressors of all types and particularly screw compressors, sliding-vane compressors, piston compressors, where the use of synthetic lubricants is recommended.
