Page 84 of 118 SGB Batch Blender with Mitsubishi Controller
6-7 Pneumatic System Maintenance
The SGB blending system uses plant-supplied compressed air to operate the
metering and dump valves on the blender.
It is the user’s responsibility to provide CLEAN AND DRY air for the blender to be
connected to. The air supply should be filtered through a 5 micron air filter and
have a water separator installed. Oil should not be used unless air dryers are
installed on the compressed air supply. In this case, an oiler may be required on
the blender to keep the air cylinder seals lubricated.
Important! As this blender uses air for blender metering functions,
it is very important to supply clean, dry air to the
blender. Dirty air can affect blender accuracy, result in
poor performance and cause injury. Provide a 5-micron
air filter on the air supply to the blender and be sure
excess oil is removed.

Sterling provides all pneumatic lines on the blender piped to a single ¼” NPT
standard pipe thread fitting. The SGB blending system requires approximately 1
cfm @ 60 psi (1.7 m³/hr @ 4.14 bar) air pressure for proper operation.
The working pressure of the blender cylinders is 60 psi. This is adjustable by the
regulator supplied on the rear panel of the blender. (It is important that the air
pressure to the blender is not fluctuating by installing the unit on an air line with
other equipment using large volumes of air. If this is the case, an accumulator
tank with a check valve may have to be provided by the customer to ensure the
blender a steady air supply.)
WARNING!
Always disconnect the compressed air supply when working
on any part of the blender.
