PRODUCT DESCRIPTION
AMSOIL Synthetic PC Series Compressor Oils are made from high
quality, shear stable synthetic base oils. PC Series oils provide long
compressor life through reduced component wear, corrosion
protection, water resistance and lubricant breakdown resistance.
These oils reduce maintenance costs by extending drain intervals and
lowering labor and used product disposal requirements.
AMSOIL Synthetic Base Oil Technology
AMSOIL’s unique formulation of synthetic base oils combine the
advantages of esters and polyalphaolefins (PAO's) into one balanced
product. The high viscosity indices, low pour points, low volatility and
prolonged thermal stability allow for use in a wide operating
temperature range. These oils minimize carbon build-up, provide clean
performance and exhibit low frictional characteristics. This superior
formulation has demonstrated increased operational efficiency,
reduced energy consumption and lower operating temperatures.
AMSOIL Compressor Oil Additives - A Thorough System for Top Performance
The anti-foam agents stop unwanted foaming and air entrainment. Corrosion inhibitors prevent
rust and corrosion caused by water and process contaminants, and oxidation inhibitors extend
lubricant life and prevent carbon formation. The PC Series is fortified with ashless, non-detergent
additives designed to increase the length of compressor serviceability.
Stable in the Presence of Water
AMSOIL PC Series exhibit very good hydrolytic stability, and they readily separate from water. This
prevents acid formation and unwanted oil/water emulsions. These features allow water to be
easily drained from the sump and extends the life of a lubricant.
Safety Advantage
AMSOIL PC Series Compressor Oils have higher flash, fire and auto-ignition points than
competitive petroleum oils. Also, their resistance to carbon formation and the ashless additive
system minimize the incidence of deposits acting as ignition-promoting hot spots. Although
AMSOIL PC Series Compressor Oils have high fire points, they cannot be considered
non-flammable.
PERFORMANCE FEATURES
Anti-foam, anti-wear protection
Rust and oxidation inhibited
Suitable for use in rotary screw, vane, centrifugal and reciprocating compressors
Combines advantages of ester and PAO technology
Excellent compatibility with components and other oils
APPLICATION RECOMMENDATION
The manufacturer's recommended viscosity grade of AMSOIL PC Series Oils is recommended for
use in single and multi-stage rotary screw, vane, centrifugal and reciprocating compressor
crankcases and cylinders, vacuum pumps and other compressor applications. In addition, the
correct viscosity may be used in light duty gear and bearing applications, blowers, pumps and
hand-held pneumatic tools.
PC Series Synthetic Compressor Oils are recommended for use in a wide temperature range,
from 20°F above the pour point to 275°F discharge temperature.
The PC Series may be used up to 8000 hours for many compressor applications.* This drain
interval is subject to operating conditions and maintenance practices. Monitoring by oil analysis at
500-hour intervals is recommended.
PC Oils are compatible with petroleum oils, most synthetic oils,** and almost all seals, paints and
materials commonly used in compressors. It is suggested that the compressor be thoroughly
drained and cleaned if warranted, and the filter be changed prior to filling with the new lubricant.
Cleaning should be done in accordance with manufacturer's recommendations. Consult AMSOIL
technical department where further recommendations are needed.
AMSOIL PRODUCT COMPATIBILITY
PC Series Compressor Oils are not recommended for "breathing air" or refrigeration
compressors; they are also not recommended for use with poly carbonate plastic that is not metal
covered, PVC plastic, butyl, ethylene-propylene and SBR rubber.
The following process gases are suitable for use with PC Series Compressor Oils: nitrogen,
hydrogen, helium, carbon monoxide, carbon dioxide (dry), ethylene, methane, propane, butane,
propylene, butylene, natural gas, benzene, butadiene, furnace (crack gas), hydrogen sulfide (dry),
sulfur hexafluoride, synthetic gas, sulfur dioxide.
AMSOIL PRODUCT AVAILABILITY
AMSOIL PC Series Compressor oils are available in 5-gallon pails, 55-gallon drums, 275-gallon
totes and bulk quantities.
