GAS AND MATERIAL COMPATIBILITY GUIDE FOR COMPRESSORS
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 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 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.
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.

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.

prior to use.
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.
