5.4 MAINTENANCE INSTRUCTIONS

COMPRESSOR FLUID
o In our compressors Shell Corena S type of oil is being used. (in some countries its called Corena D or
Comptella ÖL) This oil is specially produced oil by taking into account of compressor operation type as
you will se below.
o If you are unable to find Shell Corena S oil in your region, you may use an equivalent oil shown in the
below list. These oils are not completely equivalent to Corena S series. For this reason, if you are
having difficulty, you may need to replace the oil filter and separator together with the compressor oil.
Our experiences indicate that, when the oil residue in the separator and oil filters element are mixed
with oil of different property; this may rapidly impair the filters.

o As the chemical structures and contributions of different types of oils are different; mixing them with
each other or using them in the compressor may cause a severe damage with a high cost.
o Do not put any oil additive in the compressor oil as in the motor oils. As the oil that you use has been
prepared specially for the compressor; it already includes this type of additives.
o In case of using motor oil, hydraulic oil etc; these two types will get mixed and become paste
consistency and this immediately impairs all the filters of your compressor. If you keep operating this
way, there may be stationary damages in your screw unit in a few days.
o For this reason do not keep other lubricating oils beside your compressor. Because, your maintenance
operator may accidentally use it.
o In addition if you are in need of long life synthetic oil; contact our service and sales departments.
