The SGB blending system uses plant-supplied compressed air to operate the
metering and dump valves on the blender.
metering and dump valves on the blender.
CLEAN AND DRY air must be supplied to the blender. The air supply should be
filtered through a 5 micron air filter with a water separator. Oil should not be used
unless air dryers are installed on the compressed air supply. In this situation, 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.

cfm (1.7 m³/hr) @ 60 psi (4.14 bar) maximum air pressure for proper operation.
The working pressure of the blender cylinders is not to exceed 60 psi (4.14 bar).
This is adjustable by the regulator supplied on the rear panel of the blender. It is
important to prevent fluctuation in the air pressure to the blender by not installing
the unit on an airline. 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.
