We recommend use of GHH RAND' s fully synthetic
high performance lubricant Silol. If you use exclusively
Silol or Silol FG (foodgrade) the interval for an oil
change doubles to 12 months. The period of the
manufacturer' s w arranty is extended for new screw
compressors
to
2
years,
for
remanufactured
compressors to 1 year. Depending on the operating
conditions, branded motor oils w ith API classification
SJ/CF as per SAE J183 can also be used. The
respective viscosity class (SAE class) can be taken
from the follow ing diagram.

Oil cooler
A GHH CS750 is equipped w ith an integrated oil-cooler. If this oil-cooler is removed to
save space, the installation is equipped w ith an external oil-cooler.
An external oil-cooler is equipped w ith a 24 volt fan. The fan must be rotating during
operation and therefor the functioning of the fan must be checked during operation.
It is very important to keep the oil-cooler clean to prevent overheating of the compressor.
Observe the safety very carefully, the enclosure must be removed and rotating parts will
be accessible.
