Synthetic Compressor Oil – eliminate maintenance on compressors
Synthetic compressor oil can eliminate one maintenance chore in your shop. Most folks never change the compressor fluid in shop air compressors. These are often neglected, but critical tools in a shop. You can eliminate the need to maintain and monitor oil changes in compressors by installing synthetic compressor oil. AMSOIL PC Series Synthetic Compressor Oil is a long-life, premium compressor lubricant based on novel, proprietary technology. It incorporates the highest quality, thermally stable PAO synthetics fortified with premium non-detergent, ashless additives for maximum protection at high temperatures and pressures. It lasts up to eight times longer than petroleum oils, effectively reducing maintenance and waste oil disposal costs.
Improves Compressor Efficiency
AMSOIL PC Series Synthetic Compressor Oil has low friction properties and resists viscosity increase from oxidation. It helps improve operating efficiency and saves money on electrical energy consumption.
Synthetic Compressor Oil
Controls Foam and Reduces Wear
AMSOIL PC Series Synthetic Compressor Oil contains anti-foam additives and, unlike some other compressor oils, is anti-wear fortified. Good foam control reduces heat, oxidation and wear. High contact regions are protected against wear for increased compressor life and efficiency.
Resists Water Contamination
Water from condensation builds up in compressors and can cause unwanted oil/water emulsions, environmental discharge hazards and rust. AMSOIL PC Series Synthetic Compressor Oil is hydrolytically stable. It resists acid formation, readily separates from water and is anti-rust fortified. Water can be easily drained for simplified environmental discharge and increased oil life.
Resists Heat and Oxidation
AMSOIL PC Series Oil combines the inherent stability of premium synthetic base oils with specialized anti-oxidant additives to resist varnish, carbon and acid formation. It is formulated to protect compressors better and last longer in service than petroleum oils, especially during hot operating conditions.
Synthetic Compressor Oil
AMSOIL PC Series Oil is an ashless, high-flash-point formulation with very low carbon-forming tendencies that minimizes the incidence of ignition-promoting “hot spots.” While PC Series Oil can provide improved fire safety, it cannot be considered non-flammable.
AMSOIL PC Series Oil in the appropriate viscosity is recommended for use in single and multistage rotary screw, vane, centrifugal and reciprocating compressor crankcases and cylinders, vacuum pumps and other applications such as gears, bearings, blowers, pumps and handheld pneumatic tools. In compressor applications, drain intervals of 8,000 hours or more can be expected under normal operation. Drain intervals are subject to operating conditions and maintenance practices. Monitoring by oil analysis is recommended. For best performance when converting to AMSOIL PC Series Synthetic Compressor Oil, it is recommended the compressor be drained of the old fluid prior to the installation of PC Series Oil. If carbon deposits are present on the internal components, it is recommended they be removed following the compressor manufacturer recommendations.
How to change the air compressor oil
Some air compressors are oil less; they do NOT use oil. If you have one of those, you don’t have to change oil since there isn’t any. Most large shop style tower compressors ARE oil lubricated.
- Do NOT use regular automotive oil; this is against almost all manufacturer recommendations. Read your manual.
- Determine the weight and spec recommended.
- There will usually be a drain and a filler/dipstick.
- Drain the oil, and put the plug back in.
- Fill the oil to the level recommended on the dipstick, or on the oil sight glass.
- Most manufacturers (including CH) recommend changing once after the first hour of use.
Here is a detail of how to read the oil sight glass;
