AGIP DICREA oils are designed for the lubrication of air compressors (rotary and the reciprocating types. They are formulated from selected paraffinic base stocks treated with antioxidant antirust and antiwear additives.

PROPERTIES AND PERFORMANCE
-
AGIP DICREA lubricants are very stable at high temperature as shovvn by the low carbon residue in the DIN 51352 part 2 oxidation test. They do not form gums or carbon deposits on the hot parts of the compressor, thus minimizing ring sticking and obstruction of delivery valve ports. AGIP DICREA also have oxidation and ageing resistance and do not form sludge or deposits as shown by the results obtained in the R.O.C.O.T. test (an oxidation test designed to evaluate the oxidation resistance of lubricants for oil flooded compressors). AGIP DICREA therefore have a long service life in rotary (screw and vane) compressors.
-
They have a low carbon residue and very little tendency to form carbon on hot parts of the compressor, as demonstrated by the DIN tests.
-
They have no rust-forming tendency, and pass the ASTM D 665 A/B test.
-
AGIP DICREA are antivvear oils. They pass stage 9 in the FZG test. Antivvear properties are crucial in the lubrication of rotary compressors which are more prone to wear than reciprocating compressors owing to the way power is transmitted.
-
AGIP DICREA are compatible with most types of rubber normally used in compressor seals.
APPLICATIONS
AGIP DICREA oils are recommended for the lubrication of air compressors, including those with very high air delivery temperatures (200°C or more).
AGIP DICREA 32 and 46 have been developed specifically for rotary compressors (screw and vane).
AGIP DICREA 320 has been specially formulated for PNEUMOFORE Series F Vane Compressors.
