Pneumatic System Maintenance

The Slide Gate/Auger 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.

Note: 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.

If a dirty air filter is noticed during regular inspection intervals, replace with a new 5-micron air filter. Check the compressed air supply and ensure that the necessary steps have been taken to remove any oil from the process.

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.
