For
environmental

intake
temperatures of 40°C and more, the next
higher viscosity group should be used.
For

intake
temperatures of 5°C and less, the next
lower viscosity group should be used.
For the RFW series, single grade oils are
prescribed. Use of multi grade oils can
lead to damage of the machine.
Such use also causes the guarantee
liability of Gardner Denver to lose its
validity.
If your machine is used for suction or
compression of gases, the use of the
above listed oils may not be permissible.
Please contact us and ask about the
correct oils to use!
