Chevron CETUS® PAO

32, 46, 68, 100, 150

PRODUCT DEscriptION

Cetus® PAO oils are synthetic air compressor lubricants

formulated with high quality PAO base fluids and a high

performance additive package.

CUSTOMER BENEFITS

Cetus PAO oils deliver value through:

• Exceptional thermal and oxidation stability

— Long lubricant life in high temperature operations.

• Long machinery life and maximum

compressor efficiency — Low carbon-forming

tendency minimizes deposits.

• Long drain intervals — Long lubricant life means

less frequent oil changes.

• Minimal maintenance and downtime — Helps

promote long service intervals which can minimize

operating costs.

• Low volatility and excellent air release

tendency — Helps to reduce oil carryover

downstream and less makeup oil is needed.

FEATURES

Cetus PAO oils are synthetic air compressor lubricants

formulated with the highest quality polyalphaolefin

(PAO) base fluids.

They provide excellent thermal and oxidation stability,

high viscosity index, high flash point, low pour point,

and excellent hydrolytic stability.

Cetus PAO oils protect against rust, oxidation, and

foaming, and have ashless antiwear properties.

Cetus PAO oils are designed to meet

the requirements of modern higher

output, more efficient air compressors.

These units are more compact and

operate at higher speeds than older

compressors, resulting in higher

temperatures. As temperatures increase, deposit

formation on valves and air separators can also

increase.

The high thermal and oxidation stability extends

crankcase drain intervals compared with those

obtained with mineral oils. Compressor operators can

realize minimal equipment downtime and used oil

disposal costs.

Valve cleanliness is maintained by the excellent

thermal and oxidation stability and low carbon-forming

tendencies of this product. Clean valves help minimize

recompression, maximize compressor efficiencies and

minimize maintenance shutdown costs.

Compressor users can realize savings in maintenance

and lubrication costs through longer drain intervals

offered by Cetus PAO compared to mineral oil based

products.

In addition, they will find compatibility with most

elastomeric seal materials that are used with mineral

oil-based compressor lubricants.

APPLICATIONS

Cetus PAO oils are formulated to provide excellent

lubricating qualities for many air compressors, especially

portable and stationary rotary and screw compressors

as well as single-stage, two-stage, and

multistage reciprocating compressors.

While specific manufacturer recommendations vary,

the ISO 32, 46 and 68 grades are most commonly

used for rotary air compressors, while higher viscosity

grades are preferred for reciprocating air compressors.

Since reciprocating compressors require both a

crankcase lubricant and a cylinder lubricant, Cetus®

PAO oils are formulated to meet this dual requirement.

Cetus PAO 68 has especially been developed for the

lubrication of turbochargers in marine diesel engines,

where two separate lubricating oil systems are in

place.

Cetus PAO meet the requirements of:

• DIN 51506 VDL standard

Cetus PAO 68 is approved for:

• ABB VTR.4 turbochargers. Fulfills the requirements

as low friction lubricant for a 5000 hour drain

interval.

Do not use in high pressure systems in the vicinity of

flames, sparks and hot surfaces. Use only in well

ventilated areas. Keep container closed.

Do not use in breathing air apparatus or medical

equipment.
