Notes
Th e air fi lter and mist separator should incorporate a fl oat-type auto drain (NC) mechanism.
Use a drain tube with a diameter of at least 4 mm and length of 5 m or less. Set the tubes so that there is
no rising.
Tube Layout Notes
Tube arrangement
Use tubes with a bending radius of at least 15 mm and make sure that there are no sharp bends. Also, if the
tubes are laid parallel within the ducts for the electrical wiring or hydraulic tubes, be careful that the tubes
are not crushed by the movement of the ducts.
Tube length
To inject air simultaneously into multiple scales, make the tubes the same length from the distributor of
the air supply unit to each scale so that the injection air pressure is uniform for each scale.
Pressure setting and tube length for pressure reducing valve
If the air injection pressure for each scale is around 0.1 MPa, the air in the scale can be maintained at a low
humidity. However, setting the air injection pressure only via the pressure reducing valve will not result in
an air injection pressure of 0.1 MPa due to pressure losses stemming from the tube length.
Determine the pressure setting of the pressure reducing valve.
Adjust the air injection pressure to around 0.1 MPa so that the air consumption for each scale becomes 10
to 20 /min.
Tube fl ushing
Flush the tube from the air pressure source to the air supply unit connectors and each scale connector.
Flushing cleans the tubes, prevents the embedding of foreign objects in the equipment, and is also useful
to check the tubes.
Air pressure source
If a compressor is selected for use, take into consideration the air consumption amount (10 to 20 /min
per scale).
