Process Gas and Material Compatibility Guide for Compressors
The information presented below is meant to serve only as a guide. It is intended to provide the user with a general idea for the types of materials which have typically been compatible with the AMSOIL compressor oils, and also those materials which should have minimum contact with these products. Changes in methods of manufacture, application, degree of exposure and severity of environment can sometimes cause unpredictable effects in a material's compatibility.
PC Series
The AMSOIL PC Series
Oils are compatible with seals, paints, plastics and virtually all materials that
would be used in compressor applications. They are satisfactory for use with all
materials that are compatible with petroleum oils.
DC Series
The
AMSOIL DC Series Oils are diester-based products. This product is the focus of
the material compatibility chart. It has some compatibility issues that should
be addressed when recommending this product for an application.
Other
Compressor Oils
AMSOIL PC Series and DC Series Compressor Fluids are compatible
with petroleum, diester-based and synthetic hydrocarbon (PAO) based compressor
fluids. Glycol and silicone compressor fluids are incompatible with petroleum
and other synthetic oils, therefore also incompatible with AMSOIL Compressor Oils.
Because of the DC Series' good polarity, AMSOIL recommends using the DC Series
as a flushing agent and as the replacement compressor oil when changing out glycol
or silicone based compressor oil. To change from these types of fluid to AMSOIL,
please refer to the Procedure for Flushing Compressors. It is recommended that
a sample be taken after the system is in operation with the new fluid to ensure
a complete change out.
Seals, Paints, Plastics and Polycarbonate Bowls
AMSOIL
DC Series Compressor Oils tend to make polycarbonate bowls brittle and subject
to fracture and rupture. When using the DC Series in conjunction with polycarbonate
bowls, cover the bowls with metal bowl guards or replace them with metal bowls.
DEFINITIONS
Compatible:
hose materials which are generally unaffected by diester-based lubricants.
Marginal: Those materials for which the effect on them is dependent on their use, and composition, which can vary. Evaluation of the specific material under simulated and/or actual operating conditions is suggested prior to use.
Not Recommended: Materials which have been found to be adversely affected under most circumstances and should not be considered for use where excessive contact with the DC Series is involved.
The compatibility reference guide is directed toward the use of the DC Series Oils.
