FG---460 ISO 46 Food Grade Synthetic
* Oil changes may need to be more frequent depending on ambient conditions.
When high ambient temperatures or dirty conditions are present, oil changes may be
necessary every 1,000 hours (4,000 hours for synthetic) or even shorter intervals. Oil
change intervals required should be determined through periodic oil analysis.
General Information
KAESER synthetic lubricants should be stored in a protected location to prevent contami-
nation. Do not re---use drums; flush and send to reconditioner.
Although the KAESER synthetic is not highly flammable, it will burn. While KAESER syn-
thetic compressor oil is less flammable than equal viscosity mineral oils, it cannot be classi-
fied as a fire---resistant fluid. It has a flash point above 460•F. Since the user has total con-
trol over the conditions of the compressor lubricant, he assumes total responsibility for its
safe usage.
Material Safety Data Sheets are available for each lubricant from your KAESER authorized
distributors.
Regardless of the lubricant selected, the KAESER Sigma lubricants will separate readily
from water. If condensate occurs it can easily be removed. Let the compressor sit so that
any water can drain back to the separator tank and separate to the bottom. See chap-
ter 9.14 proper draining procedure.
Compatibility of KAESER Sigma Lubricants
All the above listed KAESER Sigma lubricants are similar to mineral oil in its compatibility
with paints, seals, gaskets and hoses. The typical precautions are required when changing
over from mineral oil to KAESER synthetic hydrocarbon based lubricant.
Never mix lubricants of different types or brands.
When switching from mineral oil to a synthetic oil, the plant's system materials must be
re---evaluated. Certain plastics are not compatible with synthetic oils. The following is a par-
tial list of acceptable and not recommended materials:
