The purpose of this paper is to inform consumers about the performance and cost differences between compressor oils, including OEM branded and popular aftermarket products. These evaluations will provide consumers the confidence in which to purchase high-quality compressor oil at the lowest possible price.

SIROCCO™ Synthetic Compressor Oil
(ISO 32/46)
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.

Package sizes include:

5-Gallon Pail
55-Gallon Drum

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. For additional information, see the AMSOIL Compatibility Guide (G-1274) or consult your AMSOIL Dealer or AMSOIL INC.

*AMSOIL SE Series is NOT RECOMMENDED as a replacement or for use with the silicone based compressor oil Sullube 24KT®. AMSOIL SE Series is NOT RECOMMENDED for use in "Breathing Air or Refrigeration" compressors.
