Dear Plant Manager:

Believe it or not a real thousand dollars is yours when you switch to AMSOIL SIROCCO® Synthetic Compressor Oil.
This is how much money you save on a drum of our compressor oil compared to Sullair Sullube 32® or Ingersoll-Rand
SSR Ultra Coolant®. And that is only the initial savings.

Each of us has different motivations. Some of us want to impress our superiors. Some of us want to look good in front
of our peers. Some of us are motivated by personal pride in a job well done or a good decision, no matter what anyone
thinks. Most of us like to make money, or save money, because of what money can buy or accomplish. What is it that
motivates you?

AMSOIL SIROCCO® Synthetic Compressor Oil is made from high quality, shear stable synthetic base oils. SIROCCO®
oil provides long compressor life through reduced component wear, corrosion protection, water resistance and
lubricant breakdown resistance. These oils reduce maintenance costs by extending drain intervals - up to 8000 hours
in many applications - and by lowering labor and used product disposal requirements. AMSOIL synthetic 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 SIROCCO® Synthetic Compressor Oil does not require extensive flushing procedures to replace
polyalkylglycol compressor fluids. Just follow your normal oil change procedures. In addition, the product is backed
fully by the AMSOIL limited warranty. AMSOIL has been a leader in lubricant technology since 1972 when it marketed
the first synthetic API certified motor oil. Today AMSOIL is a leading synthetic compressor oil manufacturer.

Performance features of our SIROCCO® Synthetic Compressor Oil include:

Anti-foam, anti-wear protection
Superior rust and oxidation prevention
Excellent compatibility with components and other oils
It's your money!
Synthetic PC Series Compressor Oils

Product Codes: PCH, PCI, PCJ, PCK, PCL


PCI - ISO 46/SAE 20 PCK - ISO 100/SAE 40

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.

(SEI) ISO-32/46





PRODUCT DESCRIPTION   

AMSOIL SE Series Synthetic Ester Compressor Oils/Coolants are formulated
with premium synthetic ester technology. These high quality, long life fluids last
several times longer in use than mineral-based oils. AMSOIL SE Series
Synthetic Ester Compressor Oils/Coolants are fully formulated with
non-detergent additives and are designed for use in rotary screw, vane and
reciprocating compressors. SE Series Synthetic Ester Compressor
Oils/Coolants increase operating efficiency, reducing money spent on energy,
repair and maintenance costs.

AMSOIL SE Series Synthetic Ester Compressor Oils/Coolants maintain
performance across a wide operating temperature range. The low pour points,
high viscosity indices and lack of paraffins (wax) make these excellent all
season lubricants. At high temperatures, SE Series Synthetic Ester Compressor
Oils/Coolants form virtually no carbon, allowing for clean operation. At cold
temperatures, equipment starts easier and the lubricant is quickly pumped to
critical components, preventing lubricant starvation and excessive wear. SE
Series Synthetic Ester Compressor Oils/Coolants also resist water to prevent
damaging oil/water emulsions, allowing for longer lubricant life and ease of
water removal from the sump.

PERFORMANCE FEATURES

Resists foaming

Rust and oxidation inhibited

Readily separates from water

Recommended for use in rotary screw and reciprocating compressors

Long-life/extended drain performance

Compatible with polyglycol fluids such as Sullube 32® and Ingersoll-Rand SSR Ultra-coolant®

SEI is biodegradable under the CEC-L33-A94 standard

SAFETY ADVANTAGE

AMSOIL SE Series Synthetic Ester Compressor Oils/Coolants have higher flash, fire and auto ignition points than
competitive petroleum oils. Their resistance to carbon formation and the ashless additive system minimize the
incidence of deposits acting as ignition-promoting hot spots. Although AMSOIL SE Series increase fire safety, they
cannot be considered non-flammable.

APPLICATION RECOMMENDATION

AMSOIL SEI is a multi-viscosity oil meeting the requirements of 5W-20. It may be used in applications calling for either
an ISO-32 or ISO-46 compressor oil or coolant. It is recommended for use in single and multi-stage rotary screw
compressors and vacuum pumps that call for this viscosity.

When installing AMSOIL SEI, it is recommended that the old oil be thoroughly drained and if warranted, the system
cleaned. If a lot of carbon or residue is found on the internal compressor parts, follow the manufacturer's
recommendations for removal prior to installing the new oil. AMSOIL SE Series Synthetic Ester Compressor
Oils/Coolants have a high level of solvency and may remove deposits left in the system. Check the filters and oil/air
separators regularly for the first 500 hours of operation and replace as necessary.

AMSOIL SEI is compatible with and recommended as a replacement for much higher priced polyalkylene glycol (PAG)
compressor oils or coolants such as Sullube 32® and Ingersoll Rand SSR Ultra Coolant®. No flushing is necessary
when changing over from Glycol Coolants to AMSOIL SEI. However, draining the system and changing the filters is
recommended.

AMSOIL SEI is recommended for use up to 8,000+ hours for most compressor applications. However, this is subject to
operating conditions and maintenance practices.* Monitoring by oil analysis every 1,000 hours is recommended.

* Where discharge temperature exceeds 205°F, lubricant life expectancy is reduced.

COMPATIBILITY
AMSOIL SEI is compatible with petroleum oils, most synthetic oils*, and many seals, paints and materials commonly
used in compressors. Materials recommended and not recommended for use with SEI oils/coolants are listed below.
