4.5.4 Gauge Indication while Operating
During operation, keep the discharge air pressure gauge indicating higher pressure.
PDSE900S ------------------------------- than
0.64MPa
PDSF830S,PDSG750S --------------- than 0.59MPa
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.
During no-load operation (at low speed), make sure to confirm that the revolution speed should
be kept higher than the under-mentioned speeds. Continuing operation at lower speed than the
under-mentioned speeds could break or damage some portions owing to vibration. If the speed
does not exceed the under-mentioned speeds, immediately stop operation. Then adjust the speed up
to the standard one.
PDSE900S,PDSF830S---------------than 1,100min

PDSG750S------------------------------ than 1,200min

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 condi-
tions and other factors.
