Instrumentation Air
The quality of instrumentation air to be supplied to this device is defined as follows.
•
Solid material: No particles with a diameter larger than 3 μm (although solid
material will be collected by the filter of this device, there should
be none in the instrumentation air)
•
Oil: Less than 1 ppm by mass
•
Supply air humidity: The dew point temperature must be at least 10 °C lower than that
of the device
From JIS C1805-1 (2001)
Referring to the above specifications, select a compressor and main line or terminal-
installation type compressed air purifier.
z
Compressed air purifier for the main line
Select a compressed air purifier for the main line, such as a main line filter or micro
coalescer from SMC, CKD, or any other leading compressed air purifier manufacturer, to
satisfy the above specifications.
z Compressed air purifier to be installed on the terminal
If measures cannot be taken on the main line due to installation of a control valve or for
other reasons, use a compressed air purifier (oil mist removal equipment/device) that can
be installed on the terminal in order to supply purified instrumentation air to this device.
