CETUS® DE32, 68, 100, 150
PRODUCT DEscriptION
Cetus® DE oils are used for portable and stationary
rotary screw, rotary vane, and reciprocating
compressors.
CUSTOMER BENEFITS
Cetus DE oils deliver value through:
• Long life — Cetus DE oils have a low sludgeforming
tendency and a high solvency for deposits
that help to keep compressor parts clean. Their
ability to minimize oil consumption, carry over,
varnish, sludge, and deposits; as well as maximize
deposit-free valve life helps minimize compressor
maintenance and energy costs.
• Ignition safety — Cetus DE oils provide a greater
margin of safety than conventional petroleum
products because their flash points, fire points, and
auto ignition temperatures are much higher. They
are not, however, true fire resistant fluids.
FEATURES
Cetus DE oils are synthetic diester-based, oxidation
resistant, compressor oils.
APPLICATIONS
Cetus DE oils are used for portable and stationary
rotary screw, rotary vane, and reciprocating
compressors. While specific manufacturer
recommendations vary, the ISO 32 and ISO 68 grades
are most commonly used for rotary compressors, while
higher viscosity grades are preferred for reciprocating
units.
These oils can be used in compressors
with the following gases: process air,
benzene, butadiene, carbon dioxide
(dry), carbon monoxide, ethylene,
furnace (crack) gas, helium,
hydrocarbon gases, hydrogen, inert
gases, methane, natural gas, nitrogen, propane, sulfur
hexafluoride, and synthesis gas.
Cetus DE oils can be used in contact with the following
seals, paints, and plastics:
• Viton
• High nitrile Buna N
• Teflon
• Epoxy paint
• Oil-resistant alkyd
• Nylon
• Delrin
• Celcon
These oils should not be used with:
• Neoprene
• SBR rubber
• Low nitrile Buna N
• Acrylic paint
• Lacquer
• Polystyrene
• PVC
• ABS
Cetus DE 100 is approved by:
• Matsubara Iron Works Co. Ltd, for use as a
reciprocating air compressor lubricant.
• Tanabe Pneumatic Machinery Co. Ltd, for use in type
H series reciprocating compressors.

Cetus® DE oils are registered by NSF and are
acceptable as lubricants where there is no possibility of
food contact (H2) in and around food processing areas.
The NSF Nonfood Compounds Registration Program is a
continuation of the USDA product approval and listing
program, which is based on meeting regulatory
requirements of appropriate use, ingredient review and
labeling verification.
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.
