4.4.4 Gauge Indication while operating
IMPORTANT...,__ ______________ _
• Minimum discharge air pressure is 58psi (4bar) during operation.
• Continuing equipment operation at a lower pressure than the above pressure may cause overheating,
since it affects the separation of lubricating oil inside the oil separator and reduces the oil flow to the
compressor air-end, resulting in temperature rise.
• Be sure to check at times to see if gauges or each component of the unit are properly working, or if
there is any air-leak, oil-leak, water-leak or fuel-leak etc.
• During normal operation, each indication of instruments is shown in the table below. Refer to the
table for daily checks.
• The above table gives standard values. They may vary slightly depending on the operating
conditions and other factors.
